Hi I have no quality issues with my Epson C900 - but it has no stopped due to it telling me I need a new transfer unit. I am not convinced and would like to know how to override this. I have looked for a counter or a fuse but cant seem to locate anything. This is definately the transfer unit not the photoconductor. We already know how to override the photoconductor. Any help would be appreciated. Thank you

When printing, as thepaper is being transported up the printer, try pressing the right door panel of the printer firmly with your hand. If the colours are much improved then the printer requires a new Transfer roller.
1. Open the Right Door.
2. Remove the Transfer Roller while opening the shaft holder (white color) levers found at the left and right shaft ends of the Transfer Roller to unlock it. Lift out the roller.
Epson C-900. There is a fuse in the photoconductor unit and the transfer unit. The photoconductor has a shorter life, so it can be a few years before the transfer unit goes end of life. I suspect the fuses are blown by the machine when the counters get to end of life limit set by the manufacturer. On both components, if the fuse is reinstated/by-passed, the machine will think it has a new part. Spare fuses are available for the photoconductor unit.
The fuse on the transfer unit is a green resistor on a small board behind a black plastic dust cover on the front edge of the transfer unit (remove 3 screws to access). Ask a friend who understands basic electric circuits if you are stumped at this point.
Of course this mechanism is there to ensure you enjoy high quality output from your printer and keep it in top condition. By over-riding the mechanism quality will deteriorate and risk of failure increases.
Just reset the toner cartridge and the machine will se it a new one. Remeber though it may now actually run out of blsack when the machine thinks it is part full. This will give quality issues when it runs low.
If you are not sure on resetting the cart, let me know.
