You just need to reset your drum counter. To do that, open up the printer and hold down the Go button for a few seconds, until the LED lights all light up (the toner, drum, and paper lights all should turn yellow). That should do the trick!

Hi there -

The reason the drum light keeps flashing is that you have to "reset" the machine after you've installed a new drum. To do this, I believe all you have to do is make sure the printer is on and then push and hold down the "GO" button a few seconds and then the flashing will stop. This will "reset" the printer to recognize you've installed a new drum. I'm going from memory on that, but I believe that's correct. It's a really simple solution. Good luck!

smearing can be interpreted different ways. if paper stalls, it will cause "stretched" print. if the drive system is bogged down by a binding drum unit or toner, it can cause a "squished" print. if its just a "blurry" kind of print, it may be generic toner. since i can't actually see defect, i would say since you replaced drum already, toner would be easiest thing to do first. keep in mind also, generic toners have a fairly high failure rate.razors

did you do the reset procedure? if not it's in your owners manual under the section "replacing the consumables". hth, razors

1) If service call occour, all four leds blink on and off (Are you in this condition?)

2) If GO and Job Cancel buttons are pressed together, the leds will be lighted up to show the error (Witch leds are lighted up after you pressed the buttons?)

Turn off the main isolation switch to your c/h system. trace the wires back to the wiring centre , check with an appropriate meter that the electrics is isolated , and swap the wires colour for colour. If you remove the 2 screws attaching the actuator to the head you will be perfectly ok to remove it. and water will not come out of the backing plate, no need to isolate the water. Sometimes the spindle on these valves seizes up so when you have the actuator off, just make sure its free by turning back and forward with a pair of grips. if its solid the whole body needs replacing which will require your system to be drained.

Check if the alignment piece of plastic that guide the blank paper on the right of the printer is fully pushed to the right of the printer ?

Hello,
This could be caused by a number of things. The first thing I would do is make sure the ethernet cable going to the printer and going from the computers to the router are not running parallel to any power cables (A/C) for more then a foot. If you need to cross an A/C cable over a cat 5 cable make sure its crossed (90 degrees) from the other cable. A/C line interference can travel pretty easy thru cat5 and can cause data transfer errors, DHCP ip renewal errors, as well as slow the data rate down by 80%, etc. I have seen this issue and know it cause cause odd behaviour to devices that used to work fine, so check that first.
If your cat5 ethernet cables is not hindered by A/C cables then another thing could be the cat5 cable itself is damaged. If you have another cat5 cable try plugging it into the printer for test purposes and try to print a document.
If that still doesn't do anything I recommend trying a firmware upgrade to your printer. You can get the latest firmware tool here:http://welcome.solutions.brother.com/bsc/public/us/ca/en/dlf/download_index.html?reg=us&c=ca&lang=en&prod=hl5250dn_all&type2=4&os=all&flang=all&dlid=
Just select your language under the heading for your operating system. Run the tool and select your printer (don't recommend doing this on wireless so make sure you do it with a PC connected via cat5 to your router).
If that still did not do anything then I suggest a setting is misconfigured on the PC's printer drivers or you may have something wrong with the printer beyond this provided solution.
Tell me how you far and I will see what else I can suggest to bring you to a resolution.
