Fusing troubles

[Voltageza]

Hi Guys

I have been struggling with this machine for over a month now.

I has intermittent fusing problems. (See attachment) Maybe twice a week.

I have:

- replaced the complete fusing unit.
- Set temp higher as per mod bulletin

The repeat is always 95mm

Bottom of the image was the leading edge. Normal 80gm paper is used.

Any ideas?

Re: Fusing troubles

if copying is paper tray type set to thick or card stock. same with printing they need to tell what paper type they are using. This will adjust fuser temp and speed should notice taking a little longer for copy to exit out.

What machine is it? The issue could be numerous things depending on model (always helpful to know this)

Hi. Machine is set to plain paper as this is plain paper. It will print one or 2 a week like this. Very seldom.

I forgot to mention this is a MPC3002

Re: Fusing troubles

Looking at your sample what makes you believe the issue is caused by the fuser?

At the bottom right the yellow point of the for sale repeats at 95mm. The fusing belt looks like the only part close to that circumference.

what else can cause this?

Re: Fusing troubles

Black drum unit is offsetting. If it were the fusing unit it would be all 4 colors being offset.

Pretty high coverage at the leading edge and in general.

Have you tried the middle thick paper type setting? it can make a difference.
Maybe look at turning fuser idling on / increasing the fuser rotational time before the first print.

Genuine toner?

But why only now and then 🤔

Re: Fusing troubles

if plain paper is it first thing in morning it happens. paper could have moisture in it from setting over night possible someone turn copier off or air conditioning being turn off. Here the thing when it happens does it continue for every print or clears up after you run copies. If that is true try to have copier fuser run before printing. I know in past could set it in service mode to have it turn on first to rotate before printing takes place.

Any idea what the SP mode is for adjusting this?

Variations in room temperature and humidity. Use of after market toner. Variations in print density, higher density print tends to offset more. If it is only occurring when printing, try using the RPCS driver and turn on toner saving.

Re: Fusing troubles

try to get service manual for copier. then in section 1 feed this is were fuser adjustments can be made there is all lot of adjustments and there is one area for printing. Easy thing is select thick for print mode when printing and see if it takes care of problem. i did not see where you could turn on the fuser before printing. they my have done away with this. Someone might know what it is and response to this question.
