Toshiba e-studio 161 fault E7-16

[resi]

I have this error in this copier; its an old unit, and the manual tells me it's "abnormal laser output" and the replacement solution is MCU PWB. What I am asking for is: does any one have a suggestion as to what I can do before I order this PCB? Pse help.

did you checked how motor with hexmirrors (in laser unit) work (is he jammed or jamming) does he have dust inside

Shomyx,

Yeah I have checked the operation of the polygon mirror in laser unit, by simulations 25-10 and 61-03. The mirror rotates. Pse give me another suggestion.

it is abnormal laser output you have check the laser pcb not the polygonmotor check also for bad connectors arround
good luck

i would take laser out first and check the mirrors for dust.... then if it is clean sub in a laser from another machine for testing...... these machines dont usually blow boards.... but lasers have been known to go in the newer models from sharp

does he have dust inside

Check visually for dust and clean. If it doesn't help change polygon motor module.
