Hp HP LaserJet IIIP+

HP IIIP accordian jam

I did the inside accordion Jam Repair Kit (two times) and the No paper Pickup repair Kit. The printer worked for about 20 sheets and now still has the accordion jam. Is there anything else I can try to repair the problem?
Is it jamming at the drum? That would indicate the drum isn't turning. You can verify that by putting a mark on the right edge of the drum with a marker. Close it up and wait for the motor to stop turning, then open and see if the mark has moved. Could be due to a bad toner cartridge. You can turn the drum manually by turning the gear with your thumb. It should turn relatively easy. If it's very stiff, then you'll need to get another cartridge.

Thank you for your reply. I have two toner cartridges from the same company. Both turn very stiffly. The mark moves sometimes and sometimes stays there. So maybe a new cartridge would fix it?

probably. doubt you could blow out 2 printer gear assemblies.

thank you for keeping a IIIP alive. i haven't fixed 1 of those in 8 years now.

drum not turning may or may not be caused by bad cartridges. like chris said, i couldn't even remember when was the last time i looked at one. from memory there's a plastic lever at the right site of the door that tends to bend and hence not allowing the drive gear to engage properly resulting in the drum not turning? moe obviously still remember them well :)

Never seen one of those plastic levers bend. If you leave the right side cover off, it's very easy to see the action of that lever when you close the door. It will move in and disengage from the gear so it can turn. Another thing to be aware of when you buy replacement cartridges is that you should not be able to read "Made in Japan" on the top cover. If you can see that, then the cartridge has not been properly rebuilt and is guaranteed to fail.
BTW, I've got 4 IIP/IIIP printers in the shop awaiting repair.

Thank you to all who have replied. I took off the right side cover to watch the gears. The plastic lever is in good shape. On start up, the clutch gears turn fine. On printing, one page will print, the gears hesitate slightly. The next page starts to print, the gears stop and accordion fold and paper jam occurs at the entrance to the drum. In both toner cartridges from the same company, the gear seems stiff but I have no other cartridge to compare stiffness. Cartridges do not say Made in Japan. Both new clutch assemblies look ok, no cracks. This printer has a page count of 109,451 and worked great up to this point. Hope to keep it in service. I hesitate to buy a new toner cartridge but will do if it will help it to work. Toner cartridge problem? Thanks.

You can't tell by watching the gears rotate. Since it's a clutch, the internal gear that drives the drum is "clutched". So if it's stopped as if by a stiff drum, it won't be visible. The only thing that would cause accordion jamming is the drum not turning, either due to a bad clutch or a seized drum.
