• HP printer trouble

    From Carlos E.R.@robin_listas@es.invalid to sci.electronics.repair on Wed Apr 16 20:23:59 2025
    From Newsgroup: sci.electronics.repair

    Hi,

    I have an HP Color LaserJet CP1515n printer since 2008-09.
    It has printed a total of 6339, according to itself. Not many pages for
    a laser, but for all these years it simply printed when I wanted it. No
    more ink trouble. I'm happy, it was a good purchase. 262re4 at the time.

    Coincidentally, the printer warns that the toner has run out. It does
    this from the page count, so it may be able to print a few hundred pages
    more before I notice printouts are going bad.

    But today it claimed to have a paper jam. I opened the paper drawer, the
    back panel, the toner drawer. No paper jam at all. I closed it again,
    the printer tried again, and after two tries it continued printing happily.

    Then I printed the second batch (the reverse side of an instruction
    book, first the odd pages, then the even pages, because this printer
    doesn't do two sides), and after 50 pages, 10 pages from the end, it
    claimed there was a jam. I repeated the procedure, no go. The noises it
    made seem like it is unable to grab the paper from the tray. So I
    powered it down, then up, and in the computer I repeated the print job
    for the 10 remaining pages, but changed the tray to number 1, which is
    the manual intake, 1 page at a time, and I could finish the job.

    What do you think it is going on?

    Maybe the paper (110 grams/m-#, explorer from www.explorer-paper.com) is
    not to its liking? It did not complain before. Try another paper. I just
    did that (80 gr/m-# plain supermarket paper) and it worked perfectly,
    printed a sample print page silently. I don't have anything longer to
    print now.

    Some roller broke down, rubber too old?

    At the price of a printer, a repair is not worth it. Maybe time to buy
    another one.

    Perhaps, but it might be worth trying some cleaning first. You can get
    sheets of cleaning paper for laser printers, and it also might be
    possible to clean the pickup roller in case it's got paper "powder" over
    it and it's slipping. Check the manual as to what can be used to clean
    the roller, but the usual thing is to use isopropyl alcohol. Further

    I have an Epson all-in-one inkjet printer that says it has a paper jamp.
    I've looked all over, can't find any paper in it. Also can't find the
    jam sensors so I could cut or short circuit one of them.

    I've had the thing, broken, for 5 or 10 years now. When I have time I
    will try to fix it again.

    Jeff's advice in the previous post is worth trying. Printers depend on
    very specific surface properties of the paper-pickup rolls. Accumulated
    dust and lint, or loss of volatile plasticizers in the rubber, lead to
    the rolls getting slick and not grabbing the paper correctly.

    Start with isopropyl alcohol to clean the rolls. Step up to stronger
    solvents if that doesn't work. Aerosol carburetor cleaner or brake
    cleaner are more potent and worth a try. If one of them works but the
    effect fades with time the trouble is likely a loss of plasticizer.

    A less-volatile cleaner might help in that case. Mineral oil in trace
    amounts softens rubber and evaporates over years. Brake fluid (ethylene
    glycol) does similar things and also evaporates relatively slowly. Either
    is worth a try if the printer is otherwise useless.

    Do be careful of brake fluid; it's a remarkably potent but very slow-
    acting solvent for common paints and finishes. If spilled, wipe it up
    right away, rinse with water (it's completely miscible) and wipe again.
    Brake fluid damage takes weeks or months to become apparent, so clean
    up promptly and completely even if damage isn't visible right away.

    Both mineral oil and brake fluid (and antifreeze, for that matter) will evaporate eventually, perhaps in a year. Annual mantenance isn't so bad.

    There are various plastic "paddle" sensors along the paper path that
    are used to detect paper jams or misfeeds. If the rubber paper feed
    roller slips slightly when trying to feet a page, the printer will
    detect that the paper is "late". The printer then declares a paper
    jam. If it correctly feeds a few pages, but then jams, my guess would
    be the same as the other Jeff's. You might have lint, dust, clay
    paper coating, loose toner, shreded paper, insects, etc that are
    causing the rubber rollers to slip on the paper.

    For the CP1515, it's likely that the rubber has been polished smooth
    by the slightly abrasive paper. That will also make the roller slip.
    Try removing the rubber part of the roller from the plastic drum and
    flipping it over. That should give the roller a 2nd life. However,
    what works every time is to purchase and install a rebuild kit. At a
    minimum, you need at least the feed roller RM1-4426 and the separation
    roller RM1-4425. For example: <https://www.ebay.com/sch/i.html?_nkw=cp1515%20rebuild%20kit>

    I can think of a few uncommon failures that might cause a paper jam
    indication. Try roller cleaning and replacement before we go down the
    rabbit hole.

    You could try that tonerbuzz tip of soaking the centre of a sheet of

    What have you got to lose, given the state of the printer?

    The suggestion of wetting a sheet of paper with your choice of solvent

    It isn't necessary to take the rollers out, just access them enough
    to squirt solvent on them. One of the long-reach nozzled found on
    aerosol brake or carb cleaner will at least help. If you can wipe
    them off that'd be better of course.

    The idea of a faulty paper sensor didn't cross my mind. I didn't think

    of lint on a photocell could conceivably be the culprit.

    was constantly needing aerosol starter fluid to start my car in the
    winter, I put a can of it in the glove compartment and ran some aquarium

    No time to answer all parts of your post, but I've read that paper is so abrasive that using scissors to cut paper will dull the scissors.
    Amazing.

    I will try first with a different brand of paper, and less weight, while
    I try to find the solvent.

    I might be able to reach the roller with my hand and tissue paper or a

    Maybe I can get a camera at the end of something long, like a medical endoscope for mechanical work. Should exist, unless it is too expensive.

    You could try that tonerbuzz tip of soaking the centre of a sheet of

    Won't it damage the... what's the name, toner cylinders when the paper
    gets to that section?

    I might be able to reach the roller with my hand and tissue paper or a

    No time to answer all parts of your post, but I've read that paper is so abrasive that using scissors to cut paper will dull the scissors.
    Amazing.

    That's why mom would get so irate when her sewing scissors were used by somebody to cut paper.

    It's certainly best not to touch the "drum", the photoconductive layer
    that forms the printed image. Whether the drum will be damaged by the
    solvent depends on the coating and solvent. But, again, what's to lose?
    If you could get the paper transport to at least try to pick up a page
    without the drum being present it'd be helpful. Also unlikely 8-(

    A volatile solvent like alcohol has a good chance of being harmless. A
    chemical softener for the rollers, like light oil or glycol-based brake
    fluid, will almost certainly wreck the drum. But, drums are wear items
    and don't last forever. It'd be worthwhile to check the price, though.


    I might be able to reach the roller with my hand and tissue paper or a brush.

    A wad of cloth taped to a stick would be better than nothing.

    Good luck, I hope you get it working!

    No. Not alcohol. What makes rubber useful is that it is ductile
    (easily stretched without breaking or lowering in material strength).
    If you "wash" rubber with alcohol, the oils that give rubber its
    ductile nature will evaporate, cause the rubber to dry out, and
    eventually make it hard as a rock. Gasoline does the same thing to

    pores. The xylene evaporates at a moderately fast rate, leaving the
    oil behind inside the rubber roller. As long as the rubber isn't
    damaged or polished smooth, the rejuvenated rubber should last a few
    years (not as long as new rubber).

    Hi,

    I have an HP Color LaserJet CP1515n printer since 2008-09.
    It has printed a total of 6339, according to itself. Not many pages for
    a laser, but for all these years it simply printed when I wanted it. No
    more ink trouble. I'm happy, it was a good purchase. 262re4 at the time.

    Coincidentally, the printer warns that the toner has run out. It does
    this from the page count, so it may be able to print a few hundred pages more before I notice printouts are going bad.

    But today it claimed to have a paper jam. I opened the paper drawer, the back panel, the toner drawer. No paper jam at all. I closed it again,
    the printer tried again, and after two tries it continued printing happily.

    Then I printed the second batch (the reverse side of an instruction
    book, first the odd pages, then the even pages, because this printer
    doesn't do two sides), and after 50 pages, 10 pages from the end, it
    claimed there was a jam. I repeated the procedure, no go. The noises it
    made seem like it is unable to grab the paper from the tray. So I
    powered it down, then up, and in the computer I repeated the print job
    for the 10 remaining pages, but changed the tray to number 1, which is
    the manual intake, 1 page at a time, and I could finish the job.

    What do you think it is going on?

    Maybe the paper (110 grams/m-#, explorer from www.explorer-paper.com) is
    not to its liking? It did not complain before. Try another paper. I just
    did that (80 gr/m-# plain supermarket paper) and it worked perfectly, printed a sample print page silently. I don't have anything longer to
    print now.

    Some roller broke down, rubber too old?

    There are rubber renew products - they are all variations of Wintergreen
    Oil. Just rub some on all the rubber rollers in your printer and let it dry.

    Do not soak the rollers or they will expand and become useless (yup!).



    At the price of a printer, a repair is not worth it. Maybe time to buy another one.


    This is a very inexpensive fix if you can find wintergreen oil.
    Otherwise MG Chemicals makes a Rubber Renue named product that is the
    same thing in a handy bottle.

    eventually make it hard as a rock. Gasoline does the same thing to
    fuel lines but takes years for the rubber to harden.

    If you want to use chemistry instead of just replacing the part, I
    suggest some made for the purpose:
    <https://www.google.com/search?q=printer%20rubber%20roller%20restorer&udm=2>
    For example:
    <https://www.precisionroller.com/category/rubber-rejuvenators.htm>
    I stuff I use is ancient and no longer sold. It's 70% xylene (banned
    in California) and 30% wintergreen oil (methyl salicylate). The
    xylene causes the pores in the rubber to enlarge. The oil fills the
    pores. The xylene evaporates at a moderately fast rate, leaving the
    oil behind inside the rubber roller. As long as the rubber isn't
    damaged or polished smooth, the rejuvenated rubber should last a few
    years (not as long as new rubber).

    If I search "Rubber Rejuvenators" in Amazon.es, I get products for the
    car instead.

    Rubber Renue by MG Chemicals: >https://mgchemicals.com/products/electronics-maintenance/specialized-cleaners/rubber-renue/
    Wintergreen Oil is the same thing, just not so easily found.

    I beg to differ. Wintergreen Oil is commonly available, but under a
    variety of names:
    <https://www.ebay.com/sch/i.html?_nkw=wintergreen%20oil>
    In retail stores, Wintergreen Oil (or Oil of Wintergreen) usually
    under beauty supplies. Also try "methyl salicylate".

    <https://mgchemicals.com/downloads/msds/01%20English%20Can-USA%20SDS/sds-408c-l.pdf>
    The MG Chemicals SDS safety sheet indicates that Rubber Renue is:
    27% methyl salicylate
    73% isopropyl alcohol
    As I previously mumbled, I don't like using alcohol. Alcohol works
    fine to soften and clean NEW rubber. It doesn't work at all with old
    rubber that has hardened. The idea is to expand the pores below the
    rubber surface and fill the pores with oil. Alcohol will not soften
    rubber that has been hardened by exposure to oxygen. I can't
    recommend a softening process without first knowing the type of rubber involved. My best guess is silicone or urethane.

    I still recommend ordering new replacement rollers.

    No. Not alcohol. What makes rubber useful is that it is ductile
    (easily stretched without breaking or lowering in material strength).

    If it's listed for use on automotive rubber parts, it will probably

    I find it difficult to believe that there is no rubber restorer
    available in Spain. Farnell sells in Spain: <https://es.farnell.com/en-ES/electrolube/rrr250/cleaner-roller-restorer-250ml/dp/1841557>
    Also, try asking people who might be using Wintergreen Oil such as practitioners of aroma therapy, beauty parlors, alternative medicine,
    etc.

    One possible reason for the lack of availability might be that there
    are shipping or mailing restrictions or regulations. Wintergreen Oil
    is somewhat toxic:
    <https://pmc.ncbi.nlm.nih.gov/articles/PMC2859737/>
    "Methyl salicylate (oil of wintergreen) contains more salicylate than
    other salicylates; 5 ml methyl salicylate is equivalent to five
    aspirin tablets (325 mg each)."

    If you have a local automotive body shop, they probably use some kind
    of rubber restorer to repair UL hardened rubbers, such as the trim
    around windows. Maybe they have a clue.

    Finally, this last product became active and I could purchase it.
    Arrived today. 7.60re4. Page says only one left in stock.

    It was shipped from Orense, which is at the opposite corner of Spain, in Galicia. That's a peculiar place, unless it arrived there by ship from
    across the pond. But somewhere I read Italy :-?
