canon ir 2318L

[smiley]

hi guys good day. any body encountered a problem on this machine when you do a copy the machine says processing but the scanner don't move the same with printing it says processing but it doesn't print when i do test print on service mode it print out the test print but if i do report print it only says processing even if i turn and off the machine the scanner still doesn't move here what i replace ip board,dc cont,cis assy with scanner motor scanner board. and still no luck. only this 2 machine doing this on the thousand ir 2318 we sell. and this is the 1st time it happened here in our country hope you can help us guys thanks a lot. smiley

what happens to scanner if u move all the way over-then power up printer ??
will it move back over on power on-?

[smiley]

no even i put it on the middle of the scanner it wont move back to its home position.

believe this printer operation is like iR2016/2020
u mean u changed Reader Motor ??-it Drives the carriage-

u need to check voltages/& signals= 24v to motor
reader motor driver controls rotation/stop and rotational direction/speed of the reader motor

[smiley]

there are no 24v supply on the drive motor of the scanner even i make a print from the pc still it doesn't print only processing appears on the control panel. only the test print on the service mode can be printed out. the error report cannot be printed. just the test print only.

try this>> power off>disconnect the FAX pcb if installed/power up ???

does your printer See the Reader connected ??

u need to check the 24v supply from Printer to Reader pcb.
and the v3.3 that supplies > to The reader motor driver -it controls rotation/stop and rotational direction/speed of the reader motor

[smiley]

you mean it is possible that the power supply are not working properly?

[teckat]

Get a volt meter and test

[smiley]

thanks teckat i will try to check it

[smiley]

hi teckat i try to check the voltage from printer to reader pcb and it has 24v on it and i test the voltage of scanner motor only 24v also there are no 3.3v on it. i replace the power supply board and still no improvement i also replace the harness from power supply to reader pcb with still no luck what do you think i should do next?

i don't have a 2318 book/ but i think the 2016/2020 is similar model

pic below is of 2016/2020 Reader - your connector layout may be similar
most important are those voltage input & output connectors/ and the communication connector to printer

SEE THE LOW VOLTAGE POWER SUPPLY CIRCUIT,for your v3.3/v5, your layout may be different/ click on pics to view

Here is the

for

iR2422/2420/2320/2318 Series

When I had the same problem with iR2018, the reader controller was wrong, caused by overwatering a plant above the copier. But you have swapped it....

[ps/pcl]

Try to do the following service mode

CS POSITION TEST
CS OUTPUT TEST (UNDER SCANNER TEST)

[smiley]

hi ps/pcl i try that cs poaition test and the cis doesn't move only the lamp goes on. and i already replace the scanner board with no improvement.

U have a voltage supply issue/ or communication issue

first check for the correct supply / do u have a volt meter ?/ do u know how to check for supply ?

Simple checks -Voltage in/ Voltage out
if all supply is good,
next step is signal communications
