Question about Xerox Phaser 7300DN Laser Printer

Pirnting quality issues


I am having a problem with Magenta streaks running through all of my full page color prints. I have checked the toner, the imaging units, cleaned the LEDs, made sure the paper type matches correctly with the media I am using, etc. Nothing seems to remove the streaks. Any suggestions...
Thanks, Dave

    Measure the front edge of the defect to the front edge of the next defect, then see what it corresponds to.

Phaser 7700 steaks on Magenta, sometimes yellow.


Each color has its own laser. Use the cleaning wand in the front door to clean the lens covers for each color. You will need to remove the waste toner cartridge in front of the the slots to do this. If that does not cure the problem, you will need to replace the developer housings for the colors that are streaking. The manual can be downloaded at: www.lpscomputer.com/ec/Phaser_7700_Service_Manual.pdf

Horz. streak approx.3/4 down on each page I print


Sounds like some of the magenta toner is left behind on the drum. The only way to fix it is to get a new cartridge.

CLP-500 vertical streaks & a horizontal line with blotches appearing randomly


I've refilled the toner cartridges a few times now and never had a problem with vertical streaks until recently. I refilled both the cyan and magenta and when I ran the test page I had dark vertical streaks on both sides. I fiddled around cleaning things, running cleaning paper through, changing reset resistors but to no avail so eventually decided to buy a replacement refurbished cyan cartridge since the streaks looked mainly blue and bingo... well almost now I just have very light magenta streaks. The issue is obvious when I compared the old and new cartridge, the replacement toner is a much duller cyan and is of the wrong consistency since once it's been in the printer everything gets covered in it which is why I think it causes the banding to occur. I'm just trying to work out now whether to try refilling the magenta again (v. messy) or just go for another refurbished cartridge (£34).

Prints black vertical line at bottom of page on every print. HP 8550gn


This should help -

Developer streak
Developer streak is characterized by a line of dark or missing toner
that stretches from the leading edge to the trailing edge. Replace the
toner cartridge corresponding to the color of the developer streak (for
example, if the streak is magenta, replace the magenta toner
cartridge).

Repetitive defects troubleshooting
Repetitive defects are defects that occur in the same vertical position
on the page, but not necessarily on every page. Most repetitive
defects are caused by problems with one of the following, and are
indicated by the positioning of the defect on the page:
 developer roller (at 38 mm)
 charging roller (at 44 mm)—see additional information under
“Charge roller set” on page 454.
 cleaning roller (at 56 mm)
 developer DSD wheels (at 65 mm)
 transfer roller (at 66 mm)
 transfer drum (occurs once per 11-by-17 inch or A3-sized page,
or every other letter- or A4-sized page)
 fuser (at 150.5 mm)
 imaging drum (at 195 mm)
 transfer belt (at 222 mm)

Those look like a problem with the imaging unit. It probably is not able to be seen by a visible inspection.
That spacing between stripes look like the diameter of the drum.
Spacing looks right.

Oki C5800 prints magenta streaks


Streaks can be caused by a number of things
The fuser
The ETB
The toner cartridge
The firmware
The printer needs a cleaning.
The slot in the printer.
Incorrect Media.

Try cleaning the printer, use a lint-free cloth for the ETB, DO NOT touch the belt with your fingers, the oil from fingers will often make things worse.
Always use a lint-free cloth, if you ever encounter dirt inside the printer, dampen the cloth.

Calibrate the printer.
From the printer's control panel menu
Configure Device-> Print Quality-> Calibrate now.
(Press the Checkmark key to advance through menus)
