9. Troubleshooting Copier Problems This section describes photocopy problems and possible solutions. Problem Solution Photocopied pages are not in correct order. On the control panel, change the [Sort] setting under copy settings to collate pages as you require. For details about [Sort], see p.257 "Copy Settings". Photocopied paper is blank. The original is not set correctly. When using the exposure glass, place originals copy side down. When using the ARDF or ADF, place them copy side up. See p.119 "Placing Originals". The wrong original was copied. If copying from the exposure glass, make sure that there are no originals in the ARDF or ADF. Copied pages come out too light. Low room temperature may have caused the machine to scan originals unclearly. Selecting [Long] for [Scan Warm-up Time] under system settings may help to improve the scanning quality. See p.279 "System Settings". Copied pages are too dark or too light. Adjust the image density. See p.170 "Adjusting Image Density". Copied pages do not look the same as the originals. Select the correct scan mode according to the type of original. See p.171 "Selecting the Document Type According to Original". Black spots appear when photocopying a photographic print. The original may have stuck to the exposure glass due to high humidity. Place the original on the exposure glass, and then place two or three sheets of white paper on top of it. Leave the ARDF or ADF open when copying. A moire pattern is produced. The original probably has heavily lined or dotted areas. Switching the setting for image quality between [Photo] and [Mixed] may eliminate the moire pattern. See p.171 "Selecting the Document Type According to Original". 390
