7014-xxx
845.01
Rear scan module cable failure or SCC card failure
CCD channel failure. Check each channel(mono,
R, G, B) for identical values indicating bad cable
and/or SCC card. Excessive noise test for the
dark data indicating some sort of CCD or analog
electronics issue on that channel or channels.
Go to
“CCD service check” on page 2-57
845.02
Cable / SCC Failure
Front scan module connector or cable failure
Go to
“CCD service check” on page 2-57
845.03
Cable / SCC Failure
Rear scan module connector or cable failure
Go to
“CCD service check” on page 2-57
845.yy
CCD Failure
The CCD is defective.
Go to
“CCD service check” on page 2-57
.
846
Front calibration strip unusable
Go to
“CCD service check” on page 2-57
846.01
Rear calibration strip unusable
846.02
Front calibration strip too far left
The font calibration strip is placed to high or to
low. Go to
“CCD service check” on page 2-57
846.03
Front calibration strip too far right
Go to
“CCD service check” on page 2-57
.
846.04
Front calibration strip has excessive skew
846.05
Front calibration strip has excessive bow
846.06
Front calibration strip has excessive dark area
Front excessive variability for Mono, Red, Green,
or Blue. Go to
“CCD service check” on
page 2-57
846.07
Front magnification exceeds limits
Rear excessive variability for Mono, Red, Green,
or Blue. Go to
“CCD service check” on
page 2-57
847
Modem Failure
The Configuration ID bit that describes the
device’s modem doesn’t match the actual modem
installed in the device.
847.01
Fax Storage
The amount of flash storage available on the
device is too small. Note: The NAND Flash
partition can shrink as bit failures cause blocks to
be invalidated. Go to
“Format Fax Storage” on
page 3-7
. If the issue is not fixed, replace the
controller board. Go to
“Controller board
removal” on page 4-8
.
847.02
Fax Storage
The devices’ flash partition is invalid or
unavailable. Go to
“Format Fax Storage” on
page 3-7
. If the issue is not fixed, replace the
controller board. Go to
“Controller board
removal” on page 4-8
.
848.01
Modem/Config ID Mismatch
A device has a modem installed, but its
Configuration ID indicates that a modem
shouldn’t be present.
849
HD/Config ID Mismatch
A device doesn’t have a hard drive installed, even
though its Configuration ID indicates that a hard
drive should be present.
