Hi all,E33Paper Jam in the First Paper Feed Area
Displayed to interrupt the machine operation:
1) If the Paper sensor has not detected paper while the Position A sensor detects the A position three times.
Recently bought a GR3750 and have been going through the steps to get it running smoothly. I'd say about 90% of the time I hit an E33 error when using regular A4 copier stock. If I run cardstock through it's more reliable. Occasionally things just work right and I can get it to crank out a bunch of pages, image is in the right place, impression is clean (but much lighter than it should be).
When it jams, the paper feeds about 2/3 of the way, you get that and then the error pops up. The drum comes down 3 times, and usually the paper just barely gets kissed by it. Then the error comes up with 1/3 of the page still under the pickup roller, and the other 2/3 under/hanging out from the guide/timing rollers.
I've been doing the feed/timing adjustments from the RA/GR service manual, but I'm still learning the timing (and terminology!) of each part as I move through.
I think the jam is occurring between when the guide & timing rollers clamp the page and when the pressure roller comes up to the drum. I do not know if this is due to slippage at the guide/timing rollers, or from the pressure roller and drum.
notes:
- I believe the timing is correct. The P-Disk notch on the bottom edge of the sensor, the Pressure Sensor Disc hole is centered on the sensor. Their cams line up with holes as appropriate.
- The stripper pad is definitely on it's last legs. I'll have a new one in a few days. Otherwise, I think I have the rest of the paper pickup system set right. It's feeding single pages and when the jam occurs it doesn't look like the pickup roller is slipping.
- I haven't tried adjusting the pressure roller or drum pressure at all, besides setting density from the front panel. I will have a new pressure roller in a few days.
- I don't have the numbers on me, but masters/copies are both pretty high (IIRC around 10k and 3 million). Not so high that the machine should be scrapped, though. I also have a stack of maintenance receipts/logs to dig through, so some of the more difficult parts that should be replaced once you get into the millions of copies may have already been replaced.
I think I can get a video sometime this weekend.
I'd love to hear any advice on what my next steps should be.
Thanks for any assistance! A lot of posts I've seen so far have been a lot of help already.
