SOURCE: 100 ITU error

Have you recently replaced the ITU? If it is saying ITU Maintenance, then the kit needs to be replaced. If you have already purchased and installed a kit, the reason this error is coming up is because the second transfer roll (small roller under the ITU) is not installed properly. Otherwise, you should purchase and install a new ITU maintenance kit.

SOURCE: my lexmark c782 keeps coming up 100.01 ITU error.

That usually means that the intermediate transfer unit(ITU) is defective but try these troubleshooting steps found in the Lexmark website. Just go to this link: http://bit.ly/dzs6o1. Follow the instructions but if all else fails, I suggest you contact Lexmark Technical Support.

SOURCE: 100.01 Services ITU Error, Lexmark

From the Lemark Service manual

A 100.01 ITU error indicates that the printer did not detect the ITU belt home sensor. Before proceeding with this

service check, make sure that the Second Transfer Roll is correctly installed. After you reinstall the Second

Transfer Roll, check to see if a 100.01 ITU error is still displayed. If a 100.01 ITU error is still being displayed,

continue with this check.

The ITU has an optical sensor that watches for a piece of reflective tape on the inside of the image belt. This

tape is read every revolution of the belt. If a signal is not received from the belt sensor within a certain time

period, the printer posts an error due to the loss of signal. There are several causes for the loss of signal. First,

the belt has tracked too far to the front or rear of the printer. In this case, the belt is still turning, but the reflective

tape is no longer passing within view of the belt sensor. This is considered a belt tracking error and is initially

posted as a 100.02 ITU Error. The other causes of a signal loss could be a belt stall, meaning the belt is not

turning, or a true signal loss, which would be due to a bad sensor, broken cable, loose connection, or bad

system board. These other causes post as a 100.01 ITU Error.

To assist the printer in determining the cause of a signal loss, there is a buffer that records the belt position for

the last 50 revolutions. If the printer loses the belt signal, it refers to the buffer. If the buffer shows significant

mistracking before signal loss, it will post a 100.02 ITU Error. If the buffer shows that the belt has been tracking

in the center before signal loss, it posts a 100.01 ITU Error. Due to memory restrictions, the buffer is not saved

during POR. This means if a printer posts a 100.02 ITU Error, so the belt is tracked off, and the customer or

servicer turns off the printer to clear the error, when the printer starts up, it will still not see the belt signal and will

now post a 100.01 ITU Error because the buffer is empty. When servicing a printer for a 100.01 ITU Error, it is

important to view the error log. See "Display Log" on page 3-29. The error log can only be displayed at this
point. Do not try to print the log. Look for past occurrences of 100.01 ITU Errors preceded by a 100.02 ITU Error.

103 service ITU ERROR


lexmark basically has said that if this error doesnt clear by powering off the machine and powering it back on again then it will need to have a service call. this error means there is a problem with the itu belt assembly.below is what they say. the steps were to pwoer it off and back on again using a grounded wall socket

This error normally requires a service call. However, certain rare occurrences, such as a stray static discharge in the vicinity of the printer or a power fluctuation, can cause a false 103 ITU error message to appear. In these cases, the error is only temporary and can be easily resolved without service. Follow the steps in the table.
Step Action 1
Power the printer off, wait ten seconds, and then power the printer back on.
Did the error message return?
Yes: Continue to step 2
No:
Print a test page. If the page prints, the printer is functioning correctly. 2
If possible, connect the printer's power cord directly into a grounded wall outlet. In rare instances, a surge protector or uninterruptible power supply (UPS) can generate false error messages.
Did the error message return?
Yes: Continue to Contacting Lexmark below.
No: Print a test page. If the page prints, the printer is functioning correctly.
