How Do You Know When the Color Developer Unit Is Bad on a Xerox Color 560
- #one
Hullo, i own a Xerox 560 got it new never used and now i noticed that kind of gradient similar on solid colors peculiarly on heavy paper (300gsm), i can't figure out where it comes from, i idea mayhap the drums simply they'r even so a 65% then any help would be welcome.

Thanks for all th info, i tried "image transfer settings" which fixed a little the black colour on a full A3 sheet. i also noticed some "bands" on the paper from feeding border to the end, information technology'due south non toner its more similar a pressure level on the paper, i am still waiting for a tech to come by and do a check.

On the 550 you'll have a PC app you tin install to employ the Density Uniformity Adjustment tool. Its on a SIQA cd.
Here'south a link for you:

Now know that you can run this tool over and over once more. Merely needed to exercise that once but in that specific case, I ran the tool v fourth dimension on a terrible paper and information technology fixed information technology completely, getting better every time I ran the tool. Most of the time 1 laissez passer works for that difficult stock.
The Image Transfer Settings you lot refer to is for when, for example, your reflex blue becomes mottle on thicker stock: the auto needs to 'pull' harder via the electric field to gather enough toner on the sheet. On the 550/C60 platform this is done on a paper range basis (aka Coated 3B for case). On the Versant its on a per stock footing which is much nicer.
Your Xerox support should be able to assistance yous with this.
Thank you and good luck

Hi Shaare thanks very much for the answer, problem is i tried SIQA and information technology says that my machine is not supported i own a Colour 560 not a C60. Also thanks for clarifying the Image Transfer choice, i don't know if those older models have some way of configuring the densitiy uniformity on the machine itself like the alignement and registration. Still waiting on that tech to spare some time for me.

Ok people i am back again with this issue now i have this on heavy stocks peculiarly similar 300gsm, what could cause that ???
Notice the totally horrible blackness density or i don't know what to phone call that plus bands or something i put a ruddy around it.

Anyone ever faced that issue ? plus i gotta mention that image and stock registration is super poor on that machine, i think we cans safely say information technology is actually horrible :southward

The drum percentage is not actually a good way of measuring drum health, so I was told by our tech. Take had drums need replacing way they were at l%, non that often of grade, simply I was told it is not very authentic and really you need to look at your prints.
- I would first try swapping out the drums and see if there is any improvement, you tin always put it back and wrap the other one up again for when y'all exercise need it.
- Do y'all have some other fuser? That would be the first thing I would be checking. I kept a fuser for 11x17 and a fuser for 12x18. Those lines remind me of fuser issues, though it has been a few years since having a machine with that type of fuser.
If your motorcar has SIQA I would recommend calibrating with that for alignment. On our old J75 information technology worked wonders... when SIQA worked (showtime three or four months and and then would never read again).

Thank you for answering guys, well the machine is new information technology was kept stored for 2 years (for many reasons) out of its box sadly, all drums and fuser and BTR are all the same from solar day one i started the machin a little less than a year agone.
Where can i see that 2d BTR i don't really know wher information technology is.
Only issue i had a while back was from Cyan Developer cake the small transparent plastic thin got a hole so information technology made a black line on all prints (not really a blank line, it had no cyan on that line).
And if it can be an issue, i noticed some "lines" on the drums i don't know if it is supposed to be like that.

I had a tech come by and according to his diagnostic it's the black drum starting to die, it'southward at 23% and i had a large B/W book run something like 60K A4 sheets overs the period of a month. Anyway to keep people updated, it's the pulsate, the cyan uniformity likewise is about probable caused by pulsate getting used.
For the marks on the paper even on unprinted areas he said information technology is likely to be the fuser roller later that much usage but it is not that big of an issue.
I take to tahnk everyone for answering me, nice from you guys, hope to learn more and more over here

We have the aforementioned outcome, the colours are banding on our 550. Getting a tech in to replace the drums fixed your result? Ours is banding on Cyan mainly allthough it seems to get better towards the centre of the printed sheet. I've been told to just employ information technology more because it's new with u.s. & that may aid atomic number 26 this out just i'one thousand not sure.
Least i know i know now that it'south not that the 550 simply tin can't do it and then thats a help.

Hello, sad we had lots of things going on.
Well the result had gone away without the drum change, looks like bad coated stock quality, and for colour uniformity i guess the auto has it's limits for meliorate solid colors on plain pages specially on coated newspaper information technology "does what it tin" lol
