Introduction This chapter explains procedures for identifying and correcting duplexer problems (troubleshooting) of both electrical and mechanical. Most of prob- lems concerning the duplex electrical may arise from defects in the interface with the printer as the duplexer is controlled by the printer itself. Section 6.2.1. Analyzing basic symptoms (electrical) on page 6-3 allows to deter- mine whether the problem is caused by a defect in the duplexer interface or in its power supply. Problems concerning paper handling, such as paper skew and paper jam are explained in Section 6.3.3. Paper jam on page 6-20. Diagram indicating the locations of major components referred to in this sec- tion is attached in Section 6.2. Electrical troubleshooting on page 6-3. 6.1.1. Setup for troubleshooting Where instructed to do so in the following sections, the duplexer must be removed from the printer and its connector must be connected to the printer's connector using the extension cable jig. Caution Before removing the duplexer from the printer or before connecting the duplexer's connector to the printer's connector using the extension cable jig, be sure to turn off printer power. Unless otherwise noted, the printer must be connected only to the duplexer during troubleshooting. No other options units (sorter, paper feeder[s]) may not be connected to the printer. 6-2 6.2. Electrical troubleshooting When a duplexer malfunction occurs, begin troubleshooting by going through the following flowchart. 6.2.1. Analyzing basic symptoms (electrical) Following this chart will allow to determine whether the problem is caused by a defect in the duplexer interface or in its power supply. This chart must be followed first of all following procedures. In following the flowchart below, the duplexer should be left installed to the printer in normal manner.
