Re: printer will not print- blank returns

Make sure carts are placed well and secured.

press menu then start bk copy then four times arrow-up (tel. index). machine switches to maintenance mode. press 7 then 6 then 4 then start bk copy. machine will refresh ink in tubes and ph and do some cleaning. after that press 7 then 6 then 3 then start bk copy. machine will do a power purge. after that leave mode by pressing 9 then 9. Run a quality test print by pressing ink etc.
If you still cant see any colors the ph has dryed out. If you see some blocks try a manual cleaning (pressing ink shift to cleaning etc.). If the next test print out still is bad the ph is clogged due to generic ink and cant be cleaned anymore. In both way ph needs replacement.

Hl4040cn will not print test page

Try doing a machine self test to ensure that it is working properly.
Press OK/return to "Machine Info"
Then down arrow once to "Test Print" and OK/Return.
The machine should produce a self test printout. If the machine does not give a print out, try cleaning the paper pick up rollers at the back of the paper tray cavity. Be careful, the machine is heavy.
If a full test print happens - Your printer is working fine and the problem is at the computer end.
It's possible driver installion is faulty or incomplete and you should try re-installing the printer driver. Is it also possible that your printer paper settings are either incorrect or do not match the paper in the printer. Check and match your paper settings in the printer preferences and the paper tray.

All my ink cartriges are full and it is asking me to replace them. I mean like really full. Printer will not print. Thank you, Wes

I'd suggest removing the cartridges, then reinserting them. That would trick the printer into thinking you added new cartridges. Hope this helps =]

Printing blank paper

At a guess you've bought a compatible generic cartrige. I had a similar problem different printer.

I had to by a genuine cartrige, worked fine. Contacted the generic cartrige provider, explained the problem. Returned cartriges and got refund no problem.

It looks like the generic cartrige makers are seeing some solutions to chipped cartridges but not all.

Dell 720 printer , new ink cartriges but prints blank pages

I know it sounds silly, but never underestimate the obvious.

Did you remove the plastic protectors from the cartridges?

Another solution maybe to return the cartridges to the store for an exchange. It has only happened once to me, but I exchanged the cartridge for another "new" one and it worked fine.

Good luck

Hi Phillip,
If you have changed the drum and toner, then check the fuser unit. The teflon coating on fuser film could be worn.

Remove the black cartridge again and remove the plastic tape where the ink comes out and then re-insert and try again.

Printing blank pages

Did you run the cart initialization?
Try this: (use new carts because it consumes some ink)
press menue then start mono (blue) then fourtimes arrow up button (tel-index). machine will be in maintenance mode and lights will flash. press 7 then 6 then 4 then start mono. machine will refill tubes and ph with freh ink and do some cleaning.
Leave maintenace by pressing 9 then 9. Do run a quality test print by pressing ink etc. Iy you cant see the letters and colored blocks well the ph has to be replaced.
I guess your machine is a 2.5 years old. Unfurtunately brother ph didnt last longer than that time when useing generic ink.

Printing and copying almost blank pages

Ussally drum/toner would fix, will not be fuser, I would suspect Hi voltage board or laser unit, In australia these machines carry a 2 year return to base warranty.

Try reseting the drum counter, this also resets Bias voltage, might be your problem. open front cover with power on and press set, arrow to change drom and select yes.

Otherwise it would be a high voltage board problem, possibility alsoexist that it could be laser unit

Check status page for "71" errors, menu * 2 8 6 4 very very fast, machine will beep "maintence displays" then 77 to print out status page, 99 to return to normal.
