The troubleshooting process The following sections identify the source of common problems that may occur with the AR-P15 and suggests ways of correcting them. The troubleshooting process The troubleshooting process is designed to eliminate the most obvious causes of failure before progressing to more complex issues. “Where problems occur” on page 28 gives an overview of the AR-P15 components and indicates areas most likely to require troubleshooting.
Where problems occur Where problems occur The AR-P15 is a built-in print server for copiers, and it is generally part of a configuration like the one shown in Figure H.
Before you go to the customer site Before you go to the customer site Before you make a service call to a customer site, talk to the customer on the phone, and try to answer the following questions: 1. Does the copier work? If the copier works, but the user cannot print the AR-P15 PCL Test page, a service call is probably required. 2.
Preliminary on-site checkout Preliminary on-site checkout Your goal in the preliminary on-site checkout is to eliminate obvious problems, such as loose or missing cables and connectors. Checking connections Before you remove the copier cover: • Check that external interface cables are plugged into the proper connectors on the side panel of the copier.
Preliminary on-site checkout TO CHECK INTERNAL CONNECTIONS 1. Before you touch any parts inside the copier, wear an ESD grounding strap and follow standard ESD (electrostatic discharge) precautions. 2. Inspect internal ribbon cables, if any, to see if they are intact. Faulty ribbon cables are easily overlooked. Check the contact point between the optional HDD cable and the HDD for separation. Make sure the HDD cable is locked into place in the connector at J207.
Preliminary on-site checkout Checking the network Printing problems may arise if the network hardware or software is not set up properly or does not match network settings on the AR-P15. Problems may also arise when printing from a specific application or printing a particular file. Most of these problems show up as printing problems and do not necessarily indicate an AR-P15 malfunction. The customer’s network administrator can eliminate many printing problems without requiring you to make a service call.
Preliminary on-site checkout If the printer does not print The following table lists possible causes and solutions when the printer does not print. Possible Cause Solutions Is the power on? Turn on the copier. Is the printer interface connector properly connected? Make sure the printer interface connector is properly connected to the copier. Is the copier online? Bring it online by touching the ON LINE icon. Is the specified paper loaded? Load the specified paper in any of the input trays.
Preliminary on-site checkout Other printing problems The following table lists other printing problems and possible solutions. 34 Problem Action An image is printed on the reverse side of the paper. Reload the paper in the paper tray upside down. Multiple pages are fed through the copier at once. Remove all the pages from the paper tray and fan them gently before reloading. Paper misfeeds occur frequently. Check the paper size settings. Use the recommended paper.
