If both enhanced fixing mode and heavy paper mode (or, transparency mode) are selected at the same time, heavy paper mode (transparency mode) will be given

priority.

9.2.12 Heavy Paper Mode

iR5065 / iR 5055 / iR5075 / / /

The machine increases fixing temperature and changes the copying/printing speed to ensure fixing on heavy paper.

A cassette for which heavy paper has been selected is used as the source of paper.

- The target temperature differs depending on the environment temperature:

if the environment temperature is 17 deg C or higher,

-> +12 deg C in relation to the target temperature.

if the environment temperature is lower than 17 deg C,

-> 217 deg C.

- The machine starts to feed paper when the reading of the main thermistor becomes identical to the target temperature.

- The copying/printing speed is as follows:

pickup from the cassette

-> 55 cpm/ppm

pickup from the manual feeder

-> 44 cpm/ppm

- If the environment temperature is lower than 17 deg C, the machine decreases the target temperature by 5 deg C every 3 min after paper feed (to as low as 192

deg C).

- If the environment temperature is 17 deg C or higher, the machine decreases the target temperature by 5 deg C every 1 min after paper feed (to as low as 192 deg C).

- If the environment temperature is less than 17 deg C, the machine executes idle rotation of the fixing roller for 1 min (to collect heat in the fixing assembly) before

starting copying/printing operation.

- If heavy paper exists together with plain paper for output, the machine holds paper at the point of registration until the target temperature for heavy paper is reached.

- If plain paper is picked up while the machine is in heavy paper mode, the machine will use the target temperature for heavy paper for fixing.

9.2.13 Transparency Mode

iR5065 / iR 5055 / iR5075 / / /

The machine increases the fixing temperature to ensure good fixing on transparencies.

- The paper type is identified as being "transparency" for the manual feed tray while the tray is used as the source of paper.

The target temperature of the fixing roller is 217 deg C.

- The machine starts paper feed d when the reading of the main thermistor becomes identical to the target temperature.

- the copying/printing speed is 44 cpm/ppm.

- if the environment temperature is lower than 17 deg C, the machine starts output 1 min after the end of start-up mode (executes initial rotation for 1 min).

- If a transparency exists among plain paper for output, the machine will hold the paper at the point of registration until the target temperature is reached.

- If plain paper is picked up while the machine is in transparency mode, the machine will continue to use the target temperature for transparencies for fixing.

If a transparency tends to wrap around the fixing roller when the machine is in transparency mode, you can improve separation by decreasing the fixing target tem-

perature for transparency mode using the following service mode item:

SERVICE MODE:

COPIER>OPTION>BODY>OHP-TEMP (Category 2)

0: normal (default)

1: -5 deg C

2: -10 deg C

3: -15 deg C

4: -20 deg C
