Punch hole mode

*1 Maximum power consumption reduction mode

Enabling this mode can lower the maximum power consumption of the machine when the main

power supply breaker is tripping due to the use of multiple printers or the power capacity of the

installation site is insufficient. For more details, refer to

Consumption.

*2 Punched hole mode

Jamming can occur with paper feeding in the [A] direction with open holes [B] at the trailing

edge as shown below. When the paper transport sensor in the optional bank detects the

punched hole:

The paper transport sensor turns OFF at the punch hole. This triggers an incorrect

detection of the trailing edge of the paper.

Next, the paper transport sensor turns ON again after the open hole passes. The

machine incorrectly detects this as the leading edge of the next sheet. This interruption

in the sequence of normal feed timing causes a paper jam.

To solve this problem:

Mask control is performed so the paper transport sensor is turned off and will not

detect again until the paper has traveled 25 mm past the sensor.

The machine goes into the punched hole mode automatically when Labels or Thick-3

are selected for the paper type because perforations are common with these paper

types frequently used by customers in the healthcare industry.

In this mode, the paper feed start timing is delayed 25 mm for each sheet, so this

slows productivity down slightly to about 29 ppm.

The distance of drum

travel between each

sheet increases, but

it is extremely small

and has no effect.
