Question about Epson AcuLaser C4100 Printer

Jam A - strange sound

I' having problems with my C4100. Usually first page after start or after standby jams and it's like the page does not go through the fuser unit (where the powder is baked to the paper) It's easy to know if there is a jam on the way because it can be heard. The printer sounds different just before it jams. When it spins up to speed the "whining" is very different if it is going to Jam. Error code is Jam A and when I open the printer the page is leaving the photo conductor unit and does not enter the fuser unit. After I clear the page and try again the printer usually sounds normal and prints very well. The service staff, where I bought the printer, can't find whats wrong and recommend a change of MOBO and more..that does cost but they are not sure if that fixes anything (I feel like a test subject, they try, I pay). Has anyone experienced this kind of failure? What can be done that does not cost as much as a new printer?? I'm now up to USD 300 and the failure still exists. Best regards Aleks

Replace fuser unit. Over time it gets dry even when not used much.

Re: Jam A - strange sound

Hi Aleks, This is a known issue on certain AcuLaser C4100 for which Epson have released a countermeasure. The problem is related to a value in the printer firmware and only realy affects the machine when it is first switched on or has sat idle for a long time whilst powered on. The fix requires a software tool to interogate the firmware and check a value. If this value is set to a certain figure it requires changing. The same software can change the value to rectify the issue. You can get the info to fix the printer from:

"P" is blinking in display Sharp AL-1641cs

There is a small white gear that drives the fuser module. It wears out at 30 to 40 thousand pages.
If the sound is a jumping to gringing noise that would be the problem.
That gear jumping will cause the machine to say out of paper,, jam,, give all kinds of problems from things bouncing around.

My 2600n laser printer had a paper jam in the outbox bin. I took the stuck paper out and had a look inside. I see no other paper jam but the printer keeps telling me I have a paper jam in the outbox. ...

There is a sensor flag (little black peice) that hangs down in the paper path as the paper exits. The flag tells the printer if the paper has made it out or not. That sounds like your problem. Just in case it is something else, her's a copy of the complete service manual for your printer. Start on page 90 (pdf page 113) and it goes thru the jam areas.,%20Service%20Manual.pdf

You may wish to switch paper types.....head down to Staples or Office Depot (or where ever) and pick up a small package of "jam free" usually states that it is 99.98% jam free... If that doesn't fix the problem, I would suggest returning the item. Best of luck!

False paper jam massage on the HP photosmart printer D5063

Your paper loading and moving mechanism in the printer seems to have some jamming problem in movement or the sensors inside the left part of the machine may have dust or inturruption somewhere.

Service your printer your own if you can, or get it service from an expert....

The high pitched whine and the paper stopping just before the fuser (the hot) unit is a known issue on the C3000 and C4100. If you are still searching for the solution to this issue, let me know, as I now have a working fix for the problem.

Dell 924

**HW support: 877-459-7298 and you must have the Express Service Code of your printer or any Dell product you're calling in so that they can route you to the right department.** Usually, if you're having paper jams, it could be a mechanical problem with the printer. Try these: - turn off the printer. unplug the power adapter for 1-2 minutes - lift the printer upside down and shake it sideways (strange huh?... usually, this helps because it can re-align those things that may not be aligned right inside the printer) - then, adjust the paper guides and use about 10-15 pieces of paper. try using the printer. if it's still the same... it really is the printer. - if it's still under warranty, Dell can replace it. This information is from Dell, try it it can't hurt.

I work with over 100 of these Ricoh printers. The MAint kit is only the fuser and does nothing to fix the problem. I have 3 in my office at the moment I am working on with new Maint kits ( fuser & 3 rollers ) snd it makes no difference. I am in the process of breaking one down and rebuilding it.
