SOURCE: printer still wont work...

You've printed a lot, havent you?

 

It seems that you have to reset the flush counter, too. The flushing box is the 2nd reason for an error unable to clean. This is the small softbox on the left hand side where the printhead runs acorss for before it starts printing. You dont have to change the flushing box. Its OK to do a reset only:

Call up maintanance modus. press 8 then 0 then several times start mono until FLUSH XXXXXXXXXX (where X are No.) appears. Press the reset code again. After leaving the maintanance mode your mfc should work without a problem.

 

BTW: What exactly did you do with the waistinktank? I hope you have replaced it by a new one!

In case you have cleaned with water and reinstalled it,  the tank wont take up ink anymore! The ink will flow into the machine and the sensor will give you the error code again (That could be another reason why you still have the error code!)

 

Please be careful and buy a new one as a sparepart from a service partner who can be found on the brother homepage of your country!

SOURCE: Error 46, 5B, and now 38

Did you deformate the pf encoder disc when reassembling the printer? This is the round foil being installed on one of the three wheels on the left side. This might be reason for the scratching sound.
5B happens when there is no ink within the purge unit tubes. It cant do a negative pressure to purge the printhead.

Try to fix the encoder disc and put some ink onto the purge station where normally the print head is in parking position. Afterwards the print engine should work again. Have ink carts placed well. The machine will try to purge the ink and is trying to do a neg. pressure again.

In case you wont be lucky you will have to go shopping to buy a new one...

error 51 = The purge cam switch does not come ON or OFF even after the purge cam has been driven by the specified number of pulses.
Fix is
Switching arm assembly not engaged correctly If the switching arm does not move smoothly, clean it.

Ink cartridge/purge switch harness not connected correctly
Correct the connection.

Purge cam switch broken Replace the purge cam switch.

Gear(s) on the maintenance unit broken Replace the maintenance unit.

Paper feed motor broken Replace the paper feed motor.

Main PCB defective. Replace the main PCB.

Cleaning of these print heads rarely if ever is successfull, they are electronic devices unlike other brands of printers

Do i need to have my 2004 dodge intrepid anti theft code reset through a dealership if the heads and head gaskets were replaced? the entire top of the engine ws taken apart adn put abcl together.


i would disconnect the battery. removing both the positive and negative battery terminals. with both ends disconnected, hold the two terminals together for about 10 seconds. this will proform a hard reset on most chrysler vehicles. also, if this doesnt work, try turning the key to the on position, and then proforming the hard reset procedure.

Reset button or Fuse on my Infinity?


Ok, I took it apart, cleared the clog out, and put it back together. It wouldn't switch to "carpet". Got no answer on my question. Took it apart again, only I went further. Took apart the bottom - brush out, all inside bottom parts out, cleaned all that part of vac. No clogs down there. Ran the carpet/bare floor switch back and forth several times while I had it apart. Put it all back together and it worked fine. Still didn't find a fuse or reset button...

Do i fix the tray that wont open on my xbox 360


Either you have something sticky spilled on your unit, or you may have to replace the motor for the disc tray. Also take note if the tray is even attempting to open at all. If so, it might just need to be cleaned.
