Canon iPF-710 error 03800500-2F30

hey everyone! hope everyone is keeping their heads above water during these tough times - stay strong!!

i have the service manual for this machine, but was hoping perhaps someone who has seen this machine/fault before could provide a few pointers on best approach so as i don't end up wasting the clients time/money

as i understand it, the head management sensor is not seeing ink discharge which could be caused by multiple issues - dirty or dead sensor, bad print head, bad carriage ribbon cable, bad main board

any suggestions or pointers are very much welcomed and appreciated!

thanks in advance!!

I know you are hoping for the sensor.... but 99 % of cases it is the head.

However get to SM and print a nozzle check. If you see a regular miss (like a block of color) than it is board + head

If you see irregular color missing - it is only the head

many thanks for your response! muchos grassy-ass

if an entire block is missing, replace both the head and the board? that's not going to be cheap! what could possibly be damaged by the head? a resistor bank on the board?

Were I to speculate I'd say the printhead took out the carriage PWB.

If an entire block is missing - I would not invest in a 710 anymore

Go for the latest TM series.

I would suggest checking the purge unit aswell. Have a look at the white absorber pads, if they are all gunky then that could be taking out the PH.

question ..... What dose an unrecoverable imagerunner (eg. c5235a, c6xxx etc) machine look like? could you send me a picture, what are the symptoms of an unrecoverable machine.? and can you just purchase a comple used set of pcbs willl that recover it?

so, i attended the machine, performed nozzle test, next to nothing printed - performed head replacement and cleaned up head, refit , machine spent half an hour refilling ink and nozzle checking repeatedly until the error returned. Reboot and & nozzle test totally blank

opened the machine up and noticed there was no ink in any of the supply tubes, in fact some yellow ink was going in the wrong direction - i assume a vacuum was created by a blockage in the ink supply someplace, valve assembly perhaps?

client informed me head and board were replaced last year, but the machine had been switched off for 3 months

didn't have time to strip the machine, remove & clean ink supply tubes, valves etc - but if you have any further pointers or suggestions before i return please feel free to share

thanks again!!

Sounds like it needs a new purge unit
