Tally 6100 missing lines - Tally Line Matrix T6100 Printer

Horizontal or vertical characters missing???
if your missing horizontal lines, look at where the print is missing if you see imprints... u have bad ribbons.
if your missing vertical characters down the page
Power off the printer & unplug from wall
Remove with phillips the top right cover. u will see that the control panel has a plastic clip needs to be pressed in for the control panel to come loose from the top right cover.
Then you will see P703 Hammerbank Ribbon Cable and
P704 Hammerbank Ribbon Cable swap these 2 cables on the Engine Controller Board part# 083368.
IF your missing characters move to another place on the printout then u will need to replace part# 083368.
IF your missing characters are still in the same place, then you will need to replace hammer module part# 081152, their is qty 11 of the individual 081152 about 1 inch wide. this will save $$$ ordering and replace 081152 if you have some at your work semi technical.
Be very careful with hands when powering the printer with the top right cover off
Electrically and mechanically.
