When we print "pages have 1/2-inch squares of color or a ghost image from a previous page". This is an exact quote of the problem listed on the Xerox Knowledge base website and is exactly what is happening when we print. Their solution is to "Turn the printer off and call for service". The problem is that the repairman is here and he doesn't seem to know what's wrong. I would think that because it is word for word what is wrong according to Xerox's website he would know what to do. Does anyone know what the problem, and better yet, what the solution is?
Thanks in advance.

Perform half test page & check for the ghost image.If half test page not showing ghost image go for 2. (Half test page:while printing open the door, take out the cartridge, remove inside paper gently) 1. check with another cartridge 2. replace teflon sleeve if available or replace fuser assembly..
Ghost images appear on
the printed page because of bad cleaning blade or improper charging of
the drum unit. Ghost images appear on the next printed page if
cleaning blade does not clean the drum surface. Drum/ photoconductor
is very sensitive to light, so special care should taken while pulling
it out. Read More here Image ghosting problem
1) try doing a full clean from within the menu on the printer, or within the computer software
2) You need to perform a half test. Put a sheet of paper on the manual feeder and do a config page from the information menu on the printer. When the back edge of the paper enters the printer, quickly open the toner door to stop the printing. Now remove the toner cartridge and look at the image below. If the defect is present, then the toner cartridge is the problem 99% of the time. There is a slight possibility that during the conditioning stage of the print process the drum of the toner is not being fully discharged so when the next stage takes places part of the previous image gets put on the toner cartridge again. Very rare. If the defect is not present then the fuser has an issue.
If your paper setting are set corectly (normal paper) and you are getting a "ghost image" from the previous page, most likley the fuser is the problem. On rare occasions, the drum unit could be the culpret (Black lines) down the sides of the page as you indicated.
You may have 2 problems.
I would change the toner drum 1st. If the black lines go away ,yet the ghost image continues, then change the fuser as well.
You have a worn image drum. The drum is the part of the printer that the print image is created on before it transfers the toner to the paper. This part is coated with a very thin layer of Teflon so the toner does not stick. When it gets worn the toner starts to stick and that produces the shadow or ghost image approximately 3 inches down the page because the diameter of the drum roller is 3 inches. You will need to get the part DR-350, Office Depot has them as well as many places on the internet.
I hope this helps, if so please rate our solution.
A laser printer is supposed to charge specific "dots" on the drum, and the toner-ink is supposed to stick only to those "dots", the paper is pressed against the drum, and then the "fuser" uses heat to "melt" the toner-ink onto the paper, to produce the printed page.
If the ghost is black then you might have a bad Black Developer 116-2011-00
If the ghost is in all colors then it may be your fuser, or possibly just your paper settings. (If you are using glossy paper or card stock this needs to be fed from the MPT tray and defined correctly in the control panel)
1. faulty wiper blade on your toner so that the previous image in not being wiped off the drum.
2. worn fuser sleve.
To work out which it is you will need to do a half stop test: print off a normal document then when it is about half way through the printer ( unfortunatly you may have to repeat this to get the timing right) open the front cover. remove the toner cartridge. if you can see the ghosting on the page the it is the toner. if its not there then its a new fuser. to save on money and if your confident enouh you may be able to just chane the fuser sleve depending on the state of the fuser on a whole.
hope this helps
