Re: My printer- Brother HL1250- is making grey streaks on...
More than likely the grey streaks are from dirty fuser rollers open the fuser area and insect the fuser rollers i think they should be grey take silicone lubricant and wiat ntil rollers cool down and clean with a coton cloth do not scrape with anything sharp if this does not work then you ned to remove the glass platen and clean the optics( mirror and lens with tissue and glass cleaner wen machine is not hot also insect expsoure lamp( do not touh lamps because the oil from your hands will cause the lamp to get extremly hot and burn out good luck
One other thought is there could be marks from the stripper fingers at the fuser section look for build up of toner on them if so clean with q tip and alcohol

If you are seeing vertical streaks/black lines your primary corona wire is dirty and or the fax scanner may be dirty. 1)To clean the corona wire you take the drum unit and toner cartridge and place it on disposable paper to avoid spilling. 2) Clean the primary corona wire inside the drum unit by sliding the blue tab from right to left several times. 3) Return the blue tab and snap it into the home position. 4) Reinstall the drum unit and toner cartridge. 5) Close the front cover. Caution: if you do not return the blue tab to the home position it may repeat the black lines.
the clean test page. Different printers produce different pages, but
you should recognize elements from the examples below on your test page.
In general, cartridge and printer problems are indicated by streaks,
missing colors, or wrong colors.
Examples from a good printer and cartridges (your test page may not look exactly like this):
Figure 1: Solid colors that match color dots on cartridge labelFigure 2: Pattern unbroken, or broken in only a few places
If your test page looks more like the good examples above than the bad
examples shown in the next two sections below, the printer and
cartridges are probably not causing the problem.

Examples from a failing printer or cartridges - streaked or broken bars or lines
Figure 3: Fading, missing, or streaked bar - low-ink or empty cartridge, clogged nozzles, or electrical problems
Figure 4: Color completely missing (magenta bar missing below)Figure 5: Lines broken randomly - clogged nozzles
Figure 6: Lines broken in pattern - dirty contacts or other electrical problems
Figure 7: Color completely missing (magenta pattern missing below)
If your test page looks like these examples, you probably have a
cartridge that is empty, has clogged nozzles, or dirty contacts.

streaking on the reverse side suggest dirty rollers.
1. remove cartridges form the printer 2. disconnect all cables 3. check full paper path for presence of debris, lint, bits of paper, remove if necessary (you can put printer on it's back or sides for esy removal) 4. mount on long skewers lint free clothing or tissue 5. wet tissue/cloth in isopropyl alcohol and whipe all rubber rollers on paper path till no discoloration to the tissue 6. connect all cables 7. insert inks and print test page
if necessary, you need to clean rollers again, but once is usually sufficient. to keep printer in good condition, you need to print at least one page per week and periodicaly clean the rollers, that depend on amount of printing done.
Description of Problem 100000013725
The ink is leaking out of the cartridge or ink leaked inside my machine.what should I do?
Description of Solution 200000017618
Brother strongly recommends that customers do not use generic ink or refill their Brother ink cartridges. Using non-Brother supplies may affect the hardware performance, print quality and machine reliability since the ink formulation in genuine Brother ink cartridges prevent smearing and clogging of the print head. The Brother limited warranty does not apply to any problem that was caused by the use of unauthorizedthird party ink and/or cartridges.
If the ink cartridge is new and has not been installed into the machine, please do not install the ink cartridge. Place the ink cartridge back into the ink cartridge packaging and call the Brother Customer Service Department at 1-800-284-4329 for assistance.
If the ink cartridge has been installed into the machine and ink has leaked inside the machine, do not remove the ink cartridge from the machine.
Please contact Brother Customer Service at 1-877-Brother (1-877-276-8437) Monday through Friday, 9:00am - 7:00pm EST, excluding holidays.
First guess is you have a bit of dirt (often white-out from people scanning corrected paper that's not quite dry) stuck on the fax scan window. This should be described pretty well in your user manual (which you can download online from brother.com).
Its also possible that there is dirt (typically loose toner) on the laser scan window (there's a laser that shines through it to get the image pattern on the drum). That window is often along the bottom of the unit under the drum/cartridge (take the cartridge out and look). The Brother manual I've seen seems to ignore this possibility.
Print streaks DO NOT mean cartridge drum replacement in many cases !!
On brother Intellifax or MFC or other laser copier/printer/fax, keep in mind that either the fax/copy
scan window OR the laser scan window can get dirty. If the fax scan
window is dirty, you see streaks on outgoing faxes and copies (but NOT
incoming faxes). If the laser scan window is dirty, you see streaks on
all prints (copies, faxes, print-from-computer).
Note also that when transporting/moving some laser copier with the toner cartridge inside, the toner can get out and make a big mess inside (including getting the laser scan window dirty). An air compressor can be usefull to blow it out. And sometimes using alcohol to clean is a BAD idea (maybe incompatible with plastic and rubber parts). A damp rag is probably fine.
Laser printers are charged using a drum which produces an electrostatic image. The drum could be unable to hold all of the 600v charge or be be scratched if the streaks are always in the same position the the drum is not holding the charge for the toner to attach to and therefore the drum is faulty and beeds to be replaced
there are two reason behind the problem. 1.drum & 2.Fuser unit.
solution no 1.
In this printer the dram attache with the tonner. at first separate the dram unit from tonner. open the drum and clean the OPC carefully and also clean the blade. and re-assemble the tonner & drum. i think it will work for u.
