Fault "blk 0 chksum error" is attributable to a corrupt firmware. Fortunately the firmware can be reloaded and restore the printer in operating condition. You can download a firmware from the tallygenicom.com site under support and drivers then download it in your PC. Normally you need to put the printer is flash download mode also instruction can be seen from the site. If you cannot do this I can assist you with this.

Error lost cpu rest

This error on the T6125 may be caused by either a hardware fault with the printer, alternatively the problem may be caused by some sort of external influence on the printer. Passable resolution to the problem include;

Hardware Fault

Locate the main logic board, check the CPU to ensure all pins are soldered correctly on the PCB. Check there is no solder over spill shorting any of the pins.
There may be a fault with the main logic board which may require replacement.

External Influence

1) External Print Server

One of the most common causes for the LOST CPU error is the use of external print servers connected to the Parallel Interface.
These printers are not reliable if connected to external print servers unless the printer parallel interface has been set Uni-Directional. To do this, you need to follow these instructions.
Set the printer to Offline.
Press the Enter and LF keys together for approx 3 - 4 seconds. The alarm will sound. (Tech Access On)
Press the Mode key: display will show Offline Normal.
Press any Arrow key until display shows Offline Config.
Press the Forms/1 key.
Press any Arrow key until display shows Config Parallel.
Press the CPI/2 key.
Press any Arrow key until display shows Parallel Bi-Dir.
Press the LPI/3 key.
Press any Arrow key until display shows Bi-Dir Off.
Press the Enter key and the interface will be set.
Press the Clear key.
Press the Enter and LF keys together for approx 3 - 4 seconds. The alarm will sound. (Tech Access Off)
On the external Print Server, you need to ensure that the unit is also set for Uni-directional working.

Electrical Interference

Check the area around the printer to ensure there is no external electrical interference eg Electric Motors, High Voltage Cables in near vicinity of the printer.

ERROR MESSAGE BLK 1CHKSUM FLT on tally t6045 printer

BLK 1 means your black toner cartridge, and I believe the chksum error may have something to do with the memory file. Check out No. 6 under Unrecoverable errors on this sheet.

This is problably something to be sent in for maintenance.

For this error these are the recomendations:
(Try cycling power; initilizing printer. If error persists, maintenance
service is indicated.)

Good luck!
