TROUBLESHOOTING Problem The connected USB memory cannot be used. The finisher / saddle stitch finisher does not operate. Stapling does not take place (including pamphlet stapling). Point to check Is the format of the USB memory FAT32? Are you using a USB memory with a capacity of more than 32 GB? Does a message appear indicating that you need to remove paper from the stapler compiler? Does the following message appear in the touch panel? "Call for service. Code:xx-xx* Please check the power of the finisher." *Letters and numbers appear in xx-xx. Have functions been disabled by the administrator? Does a message appear instructing you to check the staple unit? Does a message appear instructing you to add staples? Is a different width of paper mixed in? Are there more sheets than can be stapled at once? Is a paper size that cannot be stapled included in the print job? Is the paper type setting of the tray selected in the printer driver set to a paper type that cannot be stapled? Is the paper type setting of the selected paper tray set to heavy paper? Have functions been disabled by the administrator? Solution Check the USB memory device format. If the format of the USB memory is other than FAT32, use your computer to change the format to FAT32. Use a 32 GB or less USB memory. Remove all remaining paper from the stapler compiler. Check the finisher / saddle stitch finisher and the power plug. Remove and then firmly reinsert the power plug, and restart the machine. Check with your administrator. Some functions may have been disabled in the system settings (administrator). Remove jammed staples. ☞ "REMOVING STAPLE JAMS" (page 8-15) Replace the staple cartridge. Do not forget to replace the staple case. ☞ "REMOVING STAPLE JAMS" (page 8-15) To perform mixed size stapling, use paper of the same width and select the [Same Width] setting. Stapling is not possible when paper of different widths are mixed together. When copying, select [Same Width] from [Mixed Size Original] in the special modes. For the maximum number of sheets that can be stapled, see "SPECIFICATIONS" in the Safety Guide. For the paper sizes that can be stapled, see "SPECIFICATIONS" in the Safety Guide. Check the paper type settings in the machine and select a tray that has paper that can be used for stapling*. Click the [Tray Status] button in "Paper Selection" on the [Paper] tab of the printer properties window and check the paper type setting of each tray. * Stapling is not possible on labels, tab paper, and transparency film. In addition, if "Disable Staple" is selected in the user type, stapling will not be possible. Pamphlet stapling is not possible on heavy paper. (However, when cover insertion is selected, pamphlet stapling is possible when a single sheet of heavy paper is inserted for use as a cover.) Check with your administrator. Some functions may have been disabled in the system settings (administrator). 8-54 Contents
