- Page 81 See ‘Preventative Maintenance – PM Parts Settings’ in the service manual for full details of how to replace a PM part and check the machine after replacement.
- Page 82 If you do SP3-701-2 and replace the PCU, the counters for the PCU and all the components parts (such as the cleaning blade) will all be reset.

- Page 130 By changing over SP4-305-001 (8K/16K Detection), you can change between A4 size/letter size or Chinese paper size (8×16). If the user specifies that the lamp is too bright before scanning starts, the brightness pre-scan can be reduced by decreasing the value of SP4-309-004 (Scan Size Detect:Setting LED PWM Duty).
