Vertical streaks: Check,which color/s streaks are appearing on print out,remove that cartridge/s check on drum surface for streaks.. if found replace that cartridge/s..check. Horizontal streaks: This problem appears when the cartridge/s image drum not rotating properly. Resit the cartridges properly, print 20nos of blank pages, then check.... replace the cartridge..
Hello sir;The streak line from printing also should be from copy, because the line come from imaging unit, check the meter count if close to or over 50,000 then replace drum and drum blade, it will take care the problem.
The brother printer you need to replace imaging unit( drum unit).
check your drum unit. The toner cartridge mounts into the drum which can be permanently charged causing a constant streak to occur.
Solution: Remove the toner and drum unit. Clean them off with a non-fuzzy non-rough cloth or paper towel. Pay particular attention to where the streaks are in relation to the toner cartridge and drum. If you clean it off and you still get streaks check whether they transfer from the toner or just from the drum.
There may be a way to discharge the drum, otherwise you need a new drum.
Banded or streaked prints Solution:
Print Head Alignment MP530
Perform Print Head Alignment
to perform a Print Head Alignment directly from the machine. If
diagrams or ruled lines are misaligned, print head alignment is
required. The print head alignment can be performed automatically or manually. If the automatic print head alignment does not work, adjust the print head manually.
Automatic Print Head Alignment
Press <ON/OFF> to turn on the machine.
Load a few sheets of letter-sized plain paper in the auto sheet feeder.
the Open button to open the Paper Output Tray. Then open up and set the
extension by pressing down the hollow on the front side.
Execute automatic print head alignment.
Press <COPY> button.
Press <Menu> repeatedly to select [MAINTENACE].
the left or right cursor to select [AUTO HEAD ALIGN], then press the
<OK>. (A pattern is printed and the print head is automatically
aligned. It takes about five minutes to finish printing the pattern.)
I went to Epson.com's technology on google - and as I followed their prompts, I learned that it was the printer heads and that you aren't supposed to tilt the machine. I have been moving it a lot, so undoubtedly tilted it. You can follow the prompts after a right click on the printer icon on the bottom left corner of the monitor and it cleans the printer head. This also solves a white streak problem if people are having white streaks where there's no pringint....They had lost of answers there too.
The streaks are typically a sign of a toner drum going bad, or possibly just dirty, or even caused by the toner being low, as you have mentioned it to be. 1 way I know to 'clean' the drums is to have the printer run multiple blank pages. If your software will not allow you to print blank pages, type a single character by using this little trick, hold down the ALT key, and type 2 5 5 on the number pad in a blank text document. This will allow you to print the "blank" document, I would suggest about 10 copies. This should help for a short duration, and doesn't use any toner.
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
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)
Hi there it will be either the drum unit for the color streaks you are getting or the fuser unit. Check the drum units for the streaks on them also check the fuser but the clue is when you have the streaks in different places. Most likely to be the drum units. You will need to replace.
