[Jamming] mpc2800 fuser jams full colour only!!

[ash_572]

when customer is printing on full colour it jams in the fuser wrapping around the fusing belt even when there is an inch of white leading edge.

i replaced the fuser unit from another machine and still had the same problem. and alsochanged the exit section with no effect.

i then went out and bought a different brand of paper 80gsm and still jammed. previous paper weight was also 80gsm

i lowered the fuser temperature and still jammed inside the fuser. black and white prints are fine.

changed the paper size to landscape and it worked fine on full colour.

customer still wants it fixing on portraite so i need to go back with a solution.

anyone ideas??

thanks

Try increasing your lead edge erase margin and make sure registration is correct, are you getting wraps on your belt or on your press roller ?
I have also had success with adjusting the exit guide closer to the press roller.

i also increased the leading edge at the time when i was there and it still jammed. it wraps around the the fusing belt and sometimes underneath the metal plate guide that sits on the fusing belt. very strange

Wow. These fusers have been pretty good for me for the most part and I have never had one stick like what you describe.

Is the customer running OEM toner?

Also, you mentioned you used another fuser unit from a different machine. If you take the paper the customer is using and attempt to print/copy on that machine, does it jam? If it doesn't and the toner is the same, then it must be some settings that are different from one machine to the next.

Paper weight should not be a big issue, but perhaps try thick 1 just see what happens.

Try to adjust the entrance guide of the fusing unit. Maybe there's a bit too much buckling when the paper enters the fusing unit.

i second this solution. Have done that and it works smoothly after. No jams with FC prints.

Another reason which causes this type of issue:

Stripper Plate which is in contact with the Fuser Belt.
Once the coating on the plate worn out, the Stripper plate seems to lose its ability to 'strip'. lol. So you may want to replace it. B2384291 is the Stripper Plate for Asian Fuser.

Have you tried using thick 3 paper setting?

I understand that this is not thick paper but it slows the machine down for better fusing.

[johnyb]

Non OEM toner can cause this, It causes Havoc... Particularly on yellow prints for some reason.
If you are using IEM toner then I suggest the following. ...
Adj LE Trail Edge erase for 1and second sides.
Move the stripper plate closer to the fuser roller.
Remove the shoulder screws that stop tje fuser door going closer to tje fuser roller.

Thanks

When you say full colour, is it full coverage? Or, just a few logos/pictures/photos and text?

I second this, if my customers start printing full coverage, you can bet they'll complain of jamming and off setting. Setting the job on a thick setting remedies these issues.

Is the customer printing FC in duplex mode does it copy in FC ok?

Re: mpc2800 fuser jams full colour only!!

Is location 19 that the log is showing the jams ??

I asume that the H & P rollers etc, are in a "good"condition?

Try SP modes listed below, it seems to work for me.

Remember to reboot the device after carrying out the fusing temps adjustments.

Another thing worth trying is doing an ACC, but put the top\leading edge of the print out against the slit glass lip, NOT on the exposure glass against the guide.
It can kind of trick the device into thinking that the output is darker than it actually is. So colour \ toner concentration is reduced by by device.

[Cause]

1. The pressure roller standby temperature margin is insufficient.2. The sub scan direction trailing edge margin on 1st page is insufficient.

[Resolution]

1. Change the temperature of the pressure roller in standby mode.SP1-105-012 (Preheating1): 90 -> 80 -> 60SP1-105-013 (Preheating2): 90 -> 80 -> 60SP1-105-014 (energy saver): 90 -> 80 -> 602. Ensure the trailing edge margin is sufficient by adjusting the sub scan registration.SP1-001-002: Minus 1 mm to 2 mm(e.g. for 4.7 mm, use 2.7 mm)SP1-001-003: Minus 1 mm to 2 mm(e.g. for 4.7 mm, use 2.7 mm)3. Change amount of toner adherenceSP3-501-001 to 004: 0.444 -> 0.38

[Notes 1]

Recommended value is 80 degrees. If no results, adjust to 60 degrees. However, if the temperature is lowered, the margin for maintaining adhesive/brilliance ratio will bereduced. Therefore, please test sample output.

[Notes 2]

If the trailing edge margin is enlarged too much, it is not conducive to wrapping around the fusing roller. Adjust the image position in the direction of the paper's leadingedge while checking the output.Even if the trailing edge margin is enlarged using the settings for the trailing edge margin (SP2-103-002), the trailing edge margin may become narrow due to the sub scanregistration. Therefore, please judge the amount of margin using actual output.
