HP 4600 Paper Jams
This is going to be a little long, as I am going to try to provide all of the troubleshooting steps taken so far.
I have a HP4600 and getting Paper Tray Jams, when running multi-page documents. (Note: it has a brand new fuser.)
If I print one page at a time, it seems to work. However, when printing multi-page documents, it seems to start jamming after 3-4 pages. At first, there will be a sheet that is just entering the fuser, with another starting to feed into the ETB (1-2 inches past the lower ETB roller.
However, after clearing the jam and all paper in the transport, and checking the paper tray, it resumes printing and it jams again immediately as the paper is just under the roller at the ETB paper entrance. Clear and check tray, and it jams again (immediately) at the same location... again and again and again.
I cleared the job and started over. That's when I found that I could print one page at a time. After one page clears, I can print another and so on.
I ran a document from Tray 1 and getting the same jam, just as the 3rd page is entering the fuser.
With Tray 2, it might jam as the 3rd or 4th page is entering the fuser.
However, in both cases, when it resumes printing, the Paper Jam error occurs immediately, with the first page only 1-2" past the lower ETB roller. It may take numerous attempts before it can get the paper to feed through and complete the print job.
I'll try to explain this better, in two parts, error codes and then the mechanical aspect of the paper jam.
Error Code Events:
I printed out the event log. Most of the errors are 13.01 (Paper Feed - Paper Late) or 13.02 (Paper Feed - Paper Stopped), with 13.02 being the majority of the two. I'm not absolutely positive, but I think the first jam may sometimes be a 13.09 or 13.0A (Top Output Bin - Paper Late/Stop) error. Then, once cleared, it appears that it gets a 13.01(Paper Feed - Paper Late), then after clearing again, it consistently jams and gives a 13.02(Paper Feed - Paper Stopped) each time, until it finally is able to get a sheet through occasionally and the print job finishes.
[Note: out of the 50 error codes provide in the event log, there are two consecutive 54.12 (Density Sensor Out of Range) errors at one point, but I'm not sure that this may be indicative of the actual problem, but perhaps just a random error that was set, after the onset when one of the initial jam events occurred. It didn't show up on two subsequent tests.]
Mechanical events:
As previously mentioned, often on the first jam, there is a sheet just entering the fuser and it likely sets the Top Output error (sometimes the last sheet is barely hanging on the output of the fuser, about to drop into the output tray). However, I don't feel it is actually a jam in the fuser, as there is a sheet which is entering the ETB at the attachment roller on the bottom (it may or may not be wrinkled, as also further described below).
This problem occurs regardless of which Tray is used, although it seems to work slightly better with Tray 2 before jamming.
After clearing the jam, it immediately jams again as it tries to continue the document printing. All subsequent jams are at the bottom of the ETB. Sometimes the paper has already entered between the attachment roller and the ETB belt (usually without any noticeable wrinkling), however on some occasions it may not be under the roller and is wrinkled.
I removed the 3 color cartridges and put it into "Disable Cartridge Check".
1. Tray 1 closed - no paper
2. 6 page Print Job sent to printer - to print from Tray 2
3. Same results as before - "Paper Jam Tray 2" error -
* 1 sheet just entering the fuser
* 1 sheet approx 2" beyond the roller at the bottom of the ETB
* Paper pick-up D-rollers in a down position
4. Clear paper and allow to resume - immediate "Paper Jam Tray 2" error
* 1 sheet approx 2" beyond the roller at the bottom of ETB
5. Repeat of step #4 with same results
6. Print job finally completed

Repeat test with Tray 1
1. Tray 1 open and loaded with paper
2. 6 page Print Job sent to printer - to print from Tray 1
3. "Paper Jam Tray 1" error -
* 1 sheet just entering the fuser
* 1 sheet approx 1" to 1-1/2" beyond the roller at the bottom of the ETB
4. Clear paper and allow to resume - immediate "Paper Jam Tray 1" error
* 1 sheet approx 1" beyond the roller at the bottom of ETB
5. Cleared jam - printer went to Tray 2 and completed job - not sure why it did this.
Summary:
Color Cartridges removed
Paper Tray Jams from either Tray
Leading edge of paper is usually found 1-2 inches beyond the lower ETB roller when jam occurs.
So it seems that the problem may be related to parts that effect paper path from both Trays.
I don't have parts available to just swap out, so I'm hoping someone might be better acquainted with this printer and the likely problem.
