Xerox DC12 printing black but copy works fine

Please be clear about your problem. The Docucolor 1256GA is the same family as the Docucolor 1250/ 12 series. So there should not be any problem to print in Heavyweight Paper.

DocuColor 1632 can print on:

Plain paper (A4/210 x 297mm LEF):

? Black and white: 32 ppm; colour: 16 ppm

Transparency:

? Black and white: 13 ppm; colour: 7 ppm

Heavyweight 1 (106 to 169gsm):

? Black and white: 13 ppm; colour: 8 ppm

Heavyweight 2 (170 to 220gsm):

? Black and white: 8 ppm; colour: 8 ppm

Drum Sensore is dirty
Solution
put out first drum & see up side in near ibt belt one sensore (Small Steel Body ) Clear with Alcahol.

check that stell rod beside of fuser unit has any black toner just clean that toner

please have a check with the developer unit of the black color , it might not be moving.

for better accuracy don't replace paper in vertical, use horizental replacement of paper

If there is a shaddow on the printed documents, then it may be you drum needs replaced in the printer...

Hope this helps.....

Hi,
If you moved the printer, make sure the conections from the printer to the Fiery are secure. If loose the prints will be black but when copying will be fine.

That's a process problem with that machine.
May require a service call .ON and OFF is pretty much all a customer can do and wait for it to setup.
NOTE: The problem occurs because of the trickle development system in the machine, making extended lengths of black and white copies / prints does not allow the black developer housing to purge itself of excess waste Toner (Dry Ink) and Developer. There are two solutions for the problem:

• Make 1,000 copies / prints of a black and white job, then make 150 copies / prints of full color. Continue making 1,000 copies / prints of the black and white job, then 150 full color, and so on, until the entire black and white job is complete.
• Make extended jobs in groups of 100 by making 100 copies / prints of the black and white job, then allowing the machine to cycle down (return to 'Ready') and making the next 100 copies / prints. Continue in this pattern until the entire black and white job is complete.
