General advice on ALL copier/’printer jams…a WHOLE piece of paper in should equal a WHOLE piece of paper out. No printing device has a capability to “absorb” a stray scrap of paper. Typically, a small scrap of paper will come to rest at or near a sensor or a sensor arm (also called a flag). A “paper jam”, in most home printers, does not necessarily mean that verbatim. It’s also used as a “kitchen drawer” descriptor for anything short of software, print head or other circuity issues. Always do the following at jam-time: 1) If your unit gives a sequential removal/clearing tutorial, follow it. 2)….grab any piece of paper to be removed using BOTH HANDS,-pull EVENLY with both hands, steady pressure. If the paper begins to tear STOP, try to re-grip closer to the nip (where the two rollers meet) of the rollers, and try again. Yes, I know this seems like it takes far longer than simply yanking out the offending piece, But you won’t be left without a printer because of a scrap floating around inside.,.AND MOST IMPORTANTLY,,,Always attempt to remove paper in the same direction it was travelling. It will not always be possibly to do this. At those times, try to observe anything the paper is touching as you remove it-it is relatively easy to generate sufficient force to knock a sensor flag out of position.
ALL COPIERS AND PRINTERS——-sense jams this way…..X amount of time to be picked up from the tray, and arrive at it’s first check point, and from there, to it’s next check point. That process is repeated the entire distance through the paper path. If it fails to get there on time, VIOLA!….Le Jam.
CLEAN YOUR ROLLERS…Yes, you can do it!. Use alcohol (insert joke here)and a scrub sponge…not for some types of “foam” rollers nowadays. If you put alcohol on rubber rollers, they will get clean , and will feed the paper properly. Before you clean the rollers, feel them. If they are slippery-smooth, they are too dirty, or too old. If too old, they will become sticky when cleaned, and wont become “un-sticky” for a while, if at all.
Try to never run pre-printed paper thru again. Yes, many companies say it is OK…….IT IS DEFINITELTY NOT !!!! Every piece fed thru will leave some residue on the rollers, and pre-printed ink is worse than toner. Over a brief period, the residue builds up….then the jams start because the paper is slipping, and not quite getting to its next check point. Once the roller become impregnated, they are history. Cleaning will only be a very temporary fix.
