Hi everyone,
I have a Brother MFC-J480DW printer stuck in maintenance mode (BHL2 USB Maintenance). The screen only shows white bars, and it’s completely unresponsive. The official Firmware Update Tool doesn’t detect it, and I’ve tried multiple versions.
I’m looking for the raw firmware file LZ5313_L.blf (or .djf), compatible with FILEDG32.exe, so I can attempt a manual recovery.
If anyone has a full dump of this model (or a compatible one like MFC-J485DW or J885DW), or knows a private Discord or Telegram group where this kind of firmware is shared,...07-05-2025, 10:53 AM -
hello, I have this Brother J2730-DW printer that was brought to me by a friend, it was supposed to be converted to continues ink but the printer wouldn't turn on completely. The printer powers on and plays a tune but it gets stuck in the brother logo. Upon checking, the printer was infested by many small cockroaches. I do checked the board cleaned and tested some corroded capacitors but all seems to be fine, I couldn't find any short circuit or any missing component on the board. Also checked the power supply and it was working fine.
please help. -

Hi everyone
I have quite a bit of experience with low voltage circuits but basically none with high voltage circuits outside of recapping. So if anyone could point me in the right direction I would appreciate it very much!
This printer, history unknown, has no signs of life when plugged into 240VAC. It has the LT2988-001 board common to many Brother HL-2XXX series printers. The only physical abnormality observed is a green tint to the positive leg on the main 400V filter capacitor. This model is prone to shorts across the four Schottky diodes but all are testing OK by... -
Anyone can provide the software tools for Brother P-Touch QL-570?
According to the service manual there should exist
On the brother homepage I only can find autopoff.exe and a tool called ptsweep.exe.
I got the QL-570 as defective, but it powered up normal (voltages measured ok) with cutting and paper feed working until a paper roll and driver were installed on the connected pc.
The device now only shows a dim red LED light. Powering on/off doesn't work.
I'll do voltage measurements again to exclude an electrical/power supply problem....
