HP 4050 error 41.05

[wester]

I've got this printer that/s jamming and giving me this error, 41.05 and then also the 13.1 jam error. On the event log it gives PCL on the description. Anyone have any experience with this? Thanks in advance.

Re: HP 4050 error 41.05

Both refer to a feed delay. Have you replaced the feed tyres or cleaned them?
Possibly could also be damp paper. Is the paper not managing to get out of the tray?
The main pickup/ feed roller just clips of very easily.
Maintenance kits for these machines are very cheap and readily available that include feed rollers as well as a new fuser.

Tires are in great shape, machine only has 60k clicks on it. also I forgot to mention it prints out blank sheets along with the jam, does not apeaar to be separation or stream feed type of blanks. Paper does not seem to bee damp or anything else, also it occurs from both tray 2 and 3.

Could be Laser shutter then. When you put the top cover down it actuates a lever that opens a metal shutter from the laser. ive had these not open and close when the top cover is opened and closed. failing that laser.

Replace the feed/sep tires before going any further.

Re: HP 4050 error 41.05

you could try changing the torque limiter as well. also make sure the backstop in the tray is in the right position I recall those being a problem in that model.

Thanks for the replies. As I said tires are in real good shape, I swapped out the laser unit yesterday to no avail. I am scheduling to bring it into the shop later this week just because of the further diassembly I think is needed, its in a hospital. I seems to work fine from the bypass so I,m inclined to think it something in the feedpath for the other two trays.

Re: HP 4050 error 41.05

When you say, "in good shape" it makes me think that you didn't replace them. I've had SOOO many customers tell me the same thing. And also, you said 60,000 prints on them... which is plenty to make them stop working (torque limiter as well). Which, really, I don't see how you could possibly tell if a torque limiter is in good shape. They have a history.

As a tech, our first job is to simply eliminate the obvious possibilities. Not by looking at them to see if they're ok, but, since they're cheap, wearable parts, by replacing them.

Well, that's my opinion, anyway.

Thanks, I'm heading back there tomorrow I shall try to pop new tires on it before I bring it in. Easy enough to try.

Thanks all, turned out to be the formatter.

Re: HP 4050 error 41.05

Hmmm...been doing this job for a long time. I think the problem is everyone is thinking of the 41.3 error which is paper size error. If the paper doesn't clear the sensors at the right time it can cause that error.

My checklist for that error has always been:

1) Change 4 "D" shaped pick up rollers, 1 feed roller, 1 sep roller, & 1 torque limiter.
2) If paper continuously picks (extra sheets), replace felt on pick-up solenoid (or solenoid if defective)
3) If paper drops back into the tray, check the tray for debris or springs, and then check PF assembly behind tray 1 for debris, stuck label, or worn rollers.
4) For paper not reaching sensor in time, replace the cartridge and check the registration for debris. Usually gives 13.20 error.
5) For paper stopping in the fuser, test from tray 1 to rule out pickup issues and replace fuser. Usually gives 13.20 error.

41.5 is a Media Feed error. Which would lead you to believe it is the same as a 41.3. I would have checked the sensors behind the PF assembly that went to the engine control board. I would have thought engine control board if replacing the sensors didn't work. Still wouldn't have thought Formatter (unless it was a 4100).

41.2, 41.4, 41.9 deal with the laser scanner. A faulty shutter would give you 41.2 Beam detect error.

BTW: The service manual does not give the Formatter at all as a list of things to try.

thanks so much for the input, always welcome. I had gotten it into the shop and disassembled expecting to find something in the feed, even swapped out the feed assembly behind tray 1 feed as 1 way gear was slipping and I thought ah ha...but then it started acting up. as just a shot in the dark I tried the formatted cage assembly which seemed to cure it.. Fairly new to the HPs so thanks again for the info.. Tom(Wester)

Re: HP 4050 error 41.05

Sounds like a feed solenoid to me...the tip off was the blank page. the solenoid arm sticks and feeds and extra sheet. If you get called back that's what it is
