a. Measuring the Nip
Before measuring the nip, wait for 15 min after the end of warm-up and make 20 A4 copies:
1) Set A3 copy paper.
2) Open the copier cover.
3) Execute nip measurement mode (service mode).
The above steps will deliver a measurement sheet like the one shown in Figure 10-224.
Note:
When you execute nip measurement mode (service mode), the copy paper will stop half
way through the delivery slot. It will then be discharged fully in about 15 sec.
