FAQ

Data cannot be printed properly when the computer has only a small amount of free space available on the hard disk.

This condition occurs more easily when printing is canceled frequently.
When data is printed, a temporary file is created in /var/tmp. However, if printing is canceled before completion, the temporary file sometimes remains without being deleted.
Since the disk space becomes used up as the number of temporary files increases, use the rm command to delete files that begin with cnij.

Sometimes after a job is canceled, the next job cannot be printed properly.

The recovery procedure is described below:

1. Delete all jobs.

2. Then execute one of the following:

Turn off the machine, and then turn it back on again.

Disconnect the USB cable and then connect the cable again.

Reboot the system.

A job was canceled, but the printer did not eject the sheet that was being printed.

Execute one of the following:

Turn off the machine, and then turn it back on again.

Disconnect the USB cable and then connect the cable again.

Reboot the system.

Printing does not start.

Check whether the machine is properly connected to a computer or a network device and is ready to print.

Next, restart CUPS.

For Fedora

# /bin/systemctl restart cups.service

For Ubuntu

$ sudo service cups restart

When a large image is printed, it may take a few minutes for printing to start.

Depending on print settings, there are certain combinations that cannot be printed.

Printing is interrupted if the CUPS printer settings are changed while data is printed.

If you use the CUPS Web interface or the lpadmin command to change the CUPS printer setting while the machine is printing, the print job is forcibly canceled and printing is interrupted.
This action is a result of the CUPS specifications.

If the above condition occurs, perform the procedure below:

1. Delete all jobs.

2. Turn off the machine, and then turn it back on again.

3. Stop and then start the printer by the CUPS Web interface.

Sometimes I cannot print a document at the specified size.

The printer driver settings may have been saved with the print setting save function of another application software.

You may be able to solve this problem by opening .cups/lpoptions or .lpoptions located on the user's home directory with an editor and deleting the corresponding section.

After the printer driver is installed, the default paper size is set to Letter.

Perform the operation described below.
For instructions about installing or uninstalling a printer driver, see "Setup" in the Printer Driver Guide.

1. Uninstall the printer driver.

2. Perform the following setup procedure:

For Fedora

Open /etc/cups/cupsd.conf with an editor and add the following line at the end according to the language environment.

Example: For the English system environment:

DefaultLanguage en_GB

For Ubuntu

Open /etc/papersize with an editor and replace the paper size with the size that you want to set as the default.

Example: "Letter" -> "a4"

3. Install the printer driver again.
