SCP 1 Service Call Actions

Procedure

Throughout this manual, observe the following Warnings:

WARNING

Switch off the electricity to the machine. Disconnect the power cord from the customer supply while performing tasks that do not need electricity. Electricity can cause death or injury. Moving parts can cause injury.

WARNING Do not touch the fuser while it is hot.

WARNING

Take care during this procedure. Sharp edges may be present that can cause injury.

1. Take note of symptoms or error messages.

2. Ask the operator to describe or demonstrate the problem. 3. Make sure that:

• The power cord is connected to the wall outlet and to the machine. • All cables are connected correctly.

4. If available, check the machine service log book for any previous actions that may be relevant to the call.

5. Review any defective print or copy samples. 6. Perform ‘1 Initial Checks RAP’.

SCP 2 Final Actions

Final Actions are used to evaluate the total operation of the system and to identify the actions re-quired to complete the service call.

Procedure

• Exercise the machine in all modes.

• Make a proof copy or print of a customer document.

• If any of the customers selections were changed, return them to the customers preferred set-tings.

• Mark off any hardware/software options and modifications installed and/or enabled in the Service Log book.

• At the first service and at any subsequent service where changes are made or options are added, print the configuration report and store it with the machine log book. Discard any pre-vious versions of the configuration report.

• Remove and destroy any copies of test patterns.

• Complete the machine service log book, refer to GP 12 Service Log.

• Ensure the machine and service area are clean before leaving the customer premises. • Provide customer training if required.

WARNING:

Description

After receiving the print command there is no response at all or the print speed is low due to wrong setup of the environment rather than malfunction of the machine itself

1. Ensure you have sufficient free hard disk space for temporary work files created during printing.

1. The message ‘insufficient printer memory’ means there is a hard disk space problem on the PC, rather than a printer RAM problem. Inform the customer to secure more space on the hard disk.

2. Printing error occurs even if there is enough space in the hard disk.

2. The connection of the cable and printer port is not correct. Check the cable is properly con-nected and the parallel port in CMOS is set up correctly.

3. Set up the parallel port settings in CMOS setup.

3.Select ECP or SPP.

4. Reboot the system to print. 4. If the regular font is not printing, the cable or the printer driver may be defective.

Turn the PC and printer off, and reboot the system to print again. If not solved, double-click the printer in my computer. If the regular fonts are not printed this time install a new ca-ble.

1. Insufficient space of the hard disk in the directory assigned for the basic spool.

1. Ask the customer to delete the unneces-sary files to provide more space to start print-ing job.

2. The previous printing error is not resolved. 2. There may be files from previous failed print jobs on the hard disk with the name in the form ‘*.jnl’. Delete these files and Reboot Windows to restart the machine.

3. There may be conflict with other drivers or programs.

3. Ask the customer to shut down all other programs except the current one, if possible. 4. When an application program or the printer

driver is damaged.

4. Uninstall the print driver. Re-install the lat-est driver available at Xerox.com.

5. When some files related to OS are dam-aged or virus infected.

5. After rebooting the computer ask the cus-tomer to check for viruses, restore the dam-aged files and reinstall the application program which is not working properly. 6. Insufficient memory. 6. Ask the customer to add memory to the
