To tell if it's the fuser you can do a half way test, what you have to do is print a document, and open the front door of the printer to stop the print job half way through, you should see that half of the toner is fused to the paper and half is just applied to the paper, if you see the black lines on the fused side of the page its the fuser if you see it on the entire page it could be the etb or the cartridge.

possible fix:

This is a common issue with laser jet printer,

Try running cleaning modes under the service menu on the printer, run 5 back to back. if the issue is still showing, try using a different cartridge and run the cleaning mode again. If you have an old cartridge even if its close to being empty you can do an override on the printer to test the cartridge:
1.press ok
2.use the arrows and navigate to the system set up menu
3. press ok
4. print quality
5. press ok
6. override out
7.press ok and again ok to set

This could also be a build up of toner in the fuser assembly, and you may have to adjust the fuser temperatures in the embedded web server. You can print a blank word document (20 pages) and see if you still see black dots, if you do it is likely to be the fuser, set the driver and printer settings to card stock or heavy in order to heat the fuser more than the usual temp and print 30 blank pages this should resolve the issue. if this does not there could be damage to the ETB or the fuser assembly and servicing of the printer would be required.

take care,

Al

Horizontal line on printed page


When you use the flatbed the copy is perfect because the ccd sensor is under the glass cover and obviously is free form dust/ dirt.
On the other hand if you use the feeder the ccd sensor is located in between the roller assembly (not sure exactly for this model).
This means that the page is scanned by the ccd in the feeder, any dirt on the ccd will appear as a black line. I assume that you are feeding papers from the side and not from the top that is why you get a horizontal line.

A quick test to see if the ccd sensor is dirty is to feed the paper from the top side to the feeder. If you get a vertical line it is a proof that your ccd sensor needs to be cleaned.
The worst case is that the sensor in the feeder assembly has a tiny spot that is damaged and it is causing the black line.
So , first try the test, then open the feeder assembly, locate the ccd and clean it. Hope that this helps.

Black line on copy and fax functions


Clean the paper path for the scan/fax portion. The original goes in and as the document is "read" a spot of dirt is causing the black line down the page because it is picked up in the copy area.

Streaks and black spots on printed pages


Try cleaning the laser lens using the laser lens cleaning wand. However, it is likely that your black cartridge needs to be replaced based on the troubleshooting from the Minolta manual. Sorry,

The printer


You may need to clean the printhead: (make sure you have paper in the tray)

1) Press <Menu>

2) Press <Up> or <Down> arrow to select "Ink" then press <OK>

3) Press <Up> or <Down> arrow to select "Test print" then press <OK>

4) Press <Up> or <Down> arrow to select "Print quality" then press <OK>

5) Press the <Color Start> button. The quality test sheet will be printed. Check this printout for gaps in any of the colors or black in the pattern across the page.

6) The display on the printer will ask if the print quality is OK:

- If all lines are clear and visible, select "Yes"

- If gaps appear in the pattern, select "No"

7) If you select "No" the display asks (in turn) if the print quality is OK for black, and the three colors.

Respond "Yes" or "No" accordingly. (In this manner you may clean just the black or color nozzle that is giving you the problem)

8) The display asks if you want to start cleaning - choose "Yes"

9) After cleaning is finished press the <Color Start> button - the print quality sheet will print again.

At this point you may determine that another cleaning cycle is necessary. You may need to repeat cleanings (up to five times) to resolve the problem. Any more than that indicates a problem that may need brother customer support.

10) When the print quality test sheet meets with your approval, you may exit by pressing <Stop/Exit>

To ensure good print quality, the MFC will regularly clean the print head. You can start the cleaning process manually if needed. Clean the print head and ink cartridges if you get a horizontal line in the text or graphics on your printed pages. You can clean Black only or three colors at a time (Cyan/Yellow/Magenta), or all four colors at once.

Small group of spots repeating on page


Have you tried contacting Okidata, 2000 Bishops Gate Blvd.,Mount Laurel, N.J. 08054-4620 Phone 1-800-OKI-DATA(654-3282) or visit www.okidata.com I have a similar problem with my OKIPAGE 10e. 1 inch wide black line, 2 inches from right hand side of page from top to bottom of 8 1/2 x 11 pages. I also cleaned black dust off green roller. Problem continues. Conclusion: I'm not an expert, but I think your wiping, checking, and cleaning, is a waste of time. I think your problem, and mine, is probably not a hardware problem, although I removed my black toner cartridge out of curiosity and perhaps re-installed it incorrectly. My guess is it's some sort of electronic problem, such as programming error, or software problem.
