[Misc] IR 5055 Not recognizing the correct paper size on the glass.

[Guest]

I have an IR 5055 that when you put a LTR size paper to copy on the glass (either direction) when you close the lid the copier defaults to Legal paper. Does anyone know what this could be. I have been thru the setting but I know I am missing something that is right in front of my face I just can't put my finger on it. Any help would be appreciated.

Does this occur from the DADF also?
Clean Size Detect sensors under glass, check for correct size & orientation of cassettes 3 & 4, R & L Decks should be set for the most common size for the Country, assuming U.S. LTR?

There is a setting in service mode Level 2. Service Mode COPIER>OPTION>BODY> SENS-CNF which needs to be set to"1"

1. Enter service mode by pressing the additional functions key, #2 and #8 simultaneously, and then additional functions key again.

2. Select Level 2 Service mode (additional functions #2 Key) Copier.

select>
COPIER>OPTION>BODY> SENS-CNF
needs to be set to"1"

Power down on the control panel and power down on the right side to reboot the machine.

In Level 2 service mode COPIER>DISPLAY>SENSOR>DOC SIZE will display the size of paper on the glass when the lid/feeder is closed.

if u or someone cleared rcon/this will go to "0"
??? were u changing paper in trays from plain to heavy>back and forth ???

Next see below>>>



Check the ADF Height Adjustment / these sensors in reader> check open/close degree angle of ADF

open/closed sensor 1
open/closed sensor 2
ADF Being Closed
- When the ADF is at 25 deg or lower, the external light within the width of any original is kept out of external light, thus causing the machine to assume the absence of an original at points of external light detection (external light search operation).
The ADF open/closed sensor 2 identifies the state as being "closed," and the machine starts original size detection.
Here, B5, B4, A4, and A3 are eliminated from the list of possible sizes.
- When the external light search is over, the machine turns on the xenon lamp for the main scanning lamp, and checks the CCD (4 points) for external light. For sub scanning direction, the machine starts to operate the original sensor.
ADF Fully Closed (5 deg or less)
The machine looks for a change in the output level of individual sensors for a period of 2 sec after the ADF open/ closed sensor 1 has identified the current state as being "closed." The absence of a change in the level causes the machine to assume the presence of an original at the point in question.
The machine uses the combination of changes in the levels of 5 points to identify the size of the original in
question.

The machine identifies the size of an original with reference to the combination of measurements taken of the light reflected at specific points of the CCD and the output of a reflection type sensor. It takes measurements at 2 points for individual sizes to ensure correct identification even in the event that the original is displaced while the ADF is being closed.
- for main scanning direction, by the CCD (for AB, 8 points; for inch-configuration, 6 points)
- for sub scanning direction, by a reflection type photo-sensor (for AB-configuration, 1 point; for inch-configuration, 1 point)
The machine identifies the size of an original as follows:
1) External Light (main scanning direction only)
While keeping the scanning lamp off, the machine measures the CCD level at individual points of measurement in main scanning direction.
2) Sensor Output Level
The machine turns on the scanning lamp, and measures the CCD level at individual points of measurement in main scanning direction. Also, the machine turns on the LED of the reflection type photo-sensor in sub scanning direction to measure the sensor output. It uses the combination of the measurement and the output to identify the size of the original in question.

Thanks for your help. It looks like we have a power issue with the building. Random settings are changing in the system and after checking the power lines there are wild spikes and drops and lots of noise on the line. Electricians are repairing the lines and hopefully this will fix the issues.
