HP Laserjet 4 Plus input feed problem
I have removed and inspected the cassette pickup roller and it is in perfect condition - not really any signs of wear and rubber still nice and soft. I noticed however that there is a small black roller underneath the front left which contacts the plastic roller at the front of the paper cassette. This black rubber roller is very shiny and is apparently only meant to turn in one direction at it's connected to a clutch gear in the pick-up unit. I checked with my finger and it turns easily in the wrong direction (sometimes won't turn.... usually does).
Is it likely that this is actually the problem? If so, could you please advise me on the best course of action to rectify it. Also, is it possible to purchase a replacement for this roller.
It's not the softness of the rubber that matters, it's the grip.
You can clean the tray 1 & 2 rollers with water, or soap and water.
Best cleaner for the black rubber rollers is:
Watch the paper feed from the back of the machine with a flashlight, I think you'll be able to see if the tray 2 feed roller is picking the paper up on the first try or slipping.
The failure to transfer the paper seems to be happening when it reaches the small black roller at the front left of the printer.
I've had a look with a flashlight as suggested and the the paper is definitely stopping when it gets to the front of the cassette and the pickup roller has finished doing its thing.
I'm not quite sure how to slide the rubber with a screwdriver... it certainly rotates more than 1/8 of an inch. There's not any room between it and the black plastic at the left hand side and there's a sort of metal flange at the right had side of the rubber roller.
I have read elsewhere that this problem can be caused by a gunked-up clutch gear in the pick-up mechanism. Is this a possibility?
Today it is engaged with conceptualizing of youngsters. It is awesome action to check about the past information on the understudies and students can pay for essay online to manage their work. It is significant for creating interest. Feeling happy for having this sort of offer.
