Fusing Idling Temperature; Cpm Down System - Ricoh G179 Service Manual

temperature [C]. This prevents cold offset on the first output sheet of paper, and gives a
better first print in comparison with previous models.

Fusing Idling Temperature

If prints are not sufficiently fused soon after the main power switch is turned on, fusing
idling should be enabled with SP1103-001.
When fusing idling is enabled, it is done when the temperature reaches the print ready
("re-load") temperature. The re-load temperature can be adjusted with SP1105-003, -004.
In the opposite case, even if fusing idling is disabled, it is done when the temperature at
power-up is less than or equal to 17°C
The fusing idling time is as follows.
Temperature at
power-on
17°C or less
Higher than 17°C

6.13.9 CPM DOWN SYSTEM

When this machine gets a sequence of printing jobs, the machine uses CPM down mode to
control the printing speed, to prevent insufficient fusing temperature. The CPM down mode
is activated as following conditions below.
1. Ambient Temperature Threshold:
The machine determines whether the ambient temperature is in the 'low' condition or
'medium' condition (the threshold temperature is 17°C, which is adjustable with
SP1-916-001 to -005 for each paper type).
2. CPM Down ON/OFF Setting:
The CPM down mode can be turned on or off with the following SPs for each condition
(Low or Medium) and paper type.
Low temperature condition: SP1-916-006 to -010 (default: Off)
Medium temperature condition: SP1-916-011 to -015 (default: Off)
3. Waiting Time:
The machine decides whether the CPM down mode is activated or not after the
specified time has passed since the first sheet of paper has been fed.
Low temperature condition: SP1-916-016 to -020 (default: 60 sec.)
Medium temperature condition: SP1-916-021 to -025 (default: 60 sec.)
