7. Preventive Maintenance

When visiting the customer for a service call, perform the maintenance work to prevent any additional
problems.
Procedure for preventive maintenance
1) Check how the customer is using the machine.
2) Write down the cumulative print count.
Use the cumulative print count as a guide of replacing periodic replacement parts.
Replace the periodic replacement parts as required.
3) Print several test prints to ensure that there are no problems.
4) Remove foreign articles on BTR ASSY, FUSER ASSY and paper transfer rolls, and clean stains
with a brush and dry waste cloth.
When stains are heavy, clean with dampened cloth, and then clean with dry cloth.
Be careful not to damage the parts.
5) Cleaning the fan exhaust
Remove COVER REAR, and clean the dust on MAIN FAN with a brush.
Remove COVER FRONT, and clean the dust on FAN SUB.
The clogged exhaust and fan can result in a temperature rise internally, leading to
potential failures.
