3511 colour bleeding and fusing issue

[Mallorychan]

Hi,

I'm having some more issues with my 3511.

The first problem is I'm getting bleeding of the colours by around 2mm. Having flicked through the manual there would seem to be an abundance of things that could be causing this, what are the most common ones?

Secondly, whenever i use any paper thicker than 80gsm and any coated gloss papers the image comes out shreded and looks like the toner has been melted and scraped off? This is especially true when i try duplex.

Any help would be really appreciated.

Thanks

Do not use coated paper with this machine. Second are you setting the paper for thick 1 or thick 2 as is required? As to the registration check the main drive belts and the revolver motor backlash. Also check the revolver home sensor. Make sure the machine is completely clean.

huh? Are you saying this machine cannot except any coated papers!??

Yes, i set the thickness and have tried it on all settings. Now though, the toner is not fusing at the top of even stabdard 75gm papers as well?

Have you rebuilt the fuser? See what the thermistors look like, they may need to be replaced. If it won't fuse on standard paper I would first get the fuser rebuilt and thoroughly gone through. Then if it fuses on plain paper but will not fuse correctly on your special paper on any setting, it is a paper problem. Such is life with thicker and coated papers. The other problem you are having does sound like the drive belts are wore, there is a kit with updated gears and belts you can put it. May as well have the kit becuase the entire machine has to come apart to even see the belts very well. It's making me nauseaious thinking about it.

Hi there,

Thanks for the advice. Just an update really, i've rebuilt the fuser and replaced the drum and transfer belt and it's running a treat now in B&W but still having a problem with the colour.
The yellow toner is offsetting by about 1-2mm from the rest of the colours?
I would have thought they would all be out of allignment if the drive belts were faulty?

Any advice?

Still sounds like the drive assy. for the transfer belt. There are two belts in there that wear out, primarily the one that drives the belt. There is an updated kit, may as well have that before you tear it apart because it has to all come out of there.

<Color Deviation Correction Procedure>
There are 2 methods to correct a color deviation; using the "Test pattern 63" (correction method 1)
and using the "Test pattern 64" (correction method 2). Correct in either way of these methods.
Correction method 1
(1) While pressing the digital keys [0] and [5] simultaneously, turn the power ON.

→ (Adjustment Mode)
(2) Print out the test pattern and correct the deviation amount of the 1st page. Use the image position
of magenta (M) as a reference for correction. The image positions of yellow (Y), cyan (C) and black
(K) must be corrected with this reference.
a. Select A3/LD size. Key in “63” and then press the [FAX] button. → 2 pages of test pattern are
printed out.
b. Check the image of the 1st page and specify the color to be corrected.
c. Key in the code “417” and press the [START] button.
d. Key in the sub code of the color to be corrected and press the [START] button.
Sub code 0: Black (K) 1: Cyan (C) 3: Yellow (Y)
e. Key in the adjustment value and press the [ENTER] or [INTERRUPT] button.

Notes:

1. When the value increases by “1”, the image shifts toward the trailing edge of the paper by
0.0423 mm.
2. Adjust the image positions of black (B), cyan (C) and yellow (Y) to align the leading/trailing
edge of each image. If both leading and trailing edges are not aligned, adjust to uniform the
deviation amount of each edge.
(3) Print out the test pattern and correct the deviation amount of the 2nd page. Use the image position
of magenta (M) as a reference for correction. The image positions of yellow (Y), cyan (C) and black
(K) must be corrected with this reference.
a. Select A3/LD size. Key in “63” and then press the [FAX] button.

→ 2 pages of test pattern are
printed out.
b. Check the image of the 2nd page and specify the color to be corrected.
c. Key in the code “418” and press the [START] button.
d. Key in the sub code of the color to be corrected and press the [START] button.
Sub code 0: Black (K) 1: Cyan (C) 3: Yellow (Y)
e. Key in the adjustment value and press the [ENTER] or [INTERRUPT] button.

Notes:

1. When the value increases by “1”, the image shifts toward the trailing edge of the paper by
0.0423 mm.
2. Adjust the image positions of black (B), cyan (C) and yellow (Y) to align the leading/trailing
edge of each image. If both leading and trailing edges are not aligned, adjust to uniform the
deviation amount of each edge.

(4) Turn the power OFF.
