[Misc] Canon IRC3380 A4/A6 Scan Issue

[blackdog]

Hi there,
Looked at this box today and I'm at my wits end.
Ltr size paper on glass, go to send (scan) and A4 pops up in little ikon box.
I assume this should read AUTO.
All paper draws are set correctly.
This only happens when orignal is placed on glass to send to desktop. Copying is fine.
Result is a reduced copy sent to desktop.
How do I get my wits back.
Thanks.

Check your Original Size Detection Sensors under glass-

+ check the
Copyboard Cover Sensor=
Copyboard Cover Sensor (front, PS502; rear, PS503) Detection Signal used to indicate the state (open/closed) of the copyboard cover.

Copyboard Cover Fully Closed
After the copyboard cover sensor has identified a "closed" state, the machine checks for a change in the
output level of the original sensor (CCD point of detection) for 3 sec. If there is no change in the level of
output, the machine identifies the condition to indicate the presence of an original.
The machine uses combinations of changes in the levels of 6 locations to identify the size of the original:

check the open/closed sensor lever arm

Original sensor 1 --- original size detection (AB)
Original sensor 2 --- original size detection (Inch)

Also check the send preferances for paper size set up. Some will either default to 'A' sizes or may have been changed inadvertantly by the user, especally as you say copying is fine.

Hey thanks guys,
You know now that I am thinking of the two ORIGNAL SENSORS, I recall only seeing one.
#1 is an open slot.
Should this be?

Yes it should be open as you are in the Nth American market so it should be set up fo inch size. The combination of which sensors are covered determins what paper size is detected when on the 'Auto' select.

Daft question but did you check the send preferences on the scanning as you said in the original post copying was fine? As you knoe when scanning the send preferences decide what the user sees at the other end.

Re: Canon IRC3380 A4/A6 Scan Issue

the open/closed cover sensors both must read closed when u close down cover> if not >the correct paper size on glass reading will not function properly-

Copyboard Cover Opened
CIS: moves to point of original detection
xenon lamp: off
original sensor: off

Copyboard Cover Closed (15 deg C or more, less than 25 deg C )
a. External Light Detection
The machine executes an external light search.

b. Size Detection in Sub Scanning Direction
The copyboard cover sensor identifies a "closed" state.
CIS: at point of original detection
xenon lamp: off
original sensor: on

Copyboard Cover Closed (less than 15 deg C)
c. Size Detection in Main Scanning Direction
The machine turns on the xenon lamp inside the CIS, and uses the CCD inside the CIS to check the reflected
light.
CIS: at point of original detection
xenon lamp: on
original sensor: on

Thanks for the classroom theory.
OK, customer has three of these boxs. Two IRC3480's which have this issue and a IRC3380 which works fine.
I have to assume there is a scan setting somewhere I am missing.
I checked Model SZ in service section and that is set to inch.
Scan to mailbox and A4 pops up otherwise IRC3480's work flawlessly.
Scan to mailbox on IRC3380 and I get the correct paper setting of LETTER or 11x17.
Is there a hard reset without loosing network and customer settings?

Re: Canon IRC3380 A4/A6 Scan Issue

try this on the 3480's

keep open cover>place LTR doc. on glass>
look for that open/close cover small lever>
hold down lever>leave cover open> scan doc to mailbox

u may see a message to select paper size because of light reflection

report back

note- what happens if u scan in LTRr direction or 11x17 paper ???

When I hold down lever it will go to A3.
I'll check on the ltrr placement but I beleive that screwed up to. Go figure.
Oh this may be related.
Copy a legal size thru ADF and it will ask for 11x17 everytime and of course jam.
And when I select legal rather than auto to get it to work it will enlarge as if it were a ledger size.
Paper size flags on adf seem to be ok.
All paper drawers (two) are set to correct paper size. Letter & Legal.

Upon reviewing your posts over the past several years, I see alot of talk about drivers and firmware issues.
Could this be the problem here?
Where two same models have same issues.

Re: Canon IRC3380 A4/A6 Scan Issue

what is the firmware ver. on your printer ???

1.-ADF> needs an original paper width detection done.>in service mode
2.-ADF document size detection.think u did this already > COPIER>OPTION>BODY>MODEL-SZ> set to "1" if u use INCH only/or "3" for AB/INCH
setting value takes effect after the main power switch is turned OFF/ON.
3.-Level 2 of service mode COPIER>OPTION>BODY>ORG-LTR> should be>0: LTR
4.-Have u tried an RCON clear ?? Print out a P PRINT before doing !!
Reader Unit-Related Adjustment
RCON values are on service label (behind reader unit left cover)

5.-ADF-Related Adjustment> from P PRINT after a clear need input-
a. main scanning direction position adjustment (stream reading)
COPIER>ADJSUT>ADJ-XY>ADJ-Y-DF
b. original stop position adjustment
FEEDER>ADJSUT>DOCST
c. original feed speed (magnification) adjustment
FEEDER>ADUST>LA-SPEED
2) also Make adjustments using the following items:
a. tray width adjustment
FEEDER>FUNCTION>TRY-A4
FEEDER>FUNCTION>TRY-A5R
FEEDER>FUNCTION>TRY-LTR
FEEDER>FUNCTION>TRY-LTRR
b. CIS read position adjustment (stream reading)
COPIER>FUNCTION>INSTALL>STRD-POS
c. white level adjustment
COPIER>FUNCTION>CCD>DF-WLVL1
COPIER>FUNCTION>CCD>DF-WLVL2

Boy, someone had cleared the ram on both boxes.
Took awhile but both are running fine.
Thanks for all your input.
