Copy quality is unacceptable This section provides information about the following topics: ● Preventing problems ● Identifying and correcting copy/scan defects Note Preventing problems The following are a few simple steps you can take to improve copy quality: ● Copy from the flatbed scanner. This will produce a higher quality copy than copying from the ADF. ● Use quality originals. ● Load the media correctly. If the media is loaded incorrectly, it might skew, causing unclear images and problems with the OCR application. See the start guide for instructions. ● Open or close the straight-through output door on the device to accommodate the copy job. If you are copying to standard-weight media, use the output bin (door closed). If you are copying to heavy media, use the straight-through media path (door open). ● If your device frequently feeds more than one page at a time, replace the separation pad. For more information, see Replacing the device separation pad. ● Use or make a carrier sheet to protect your originals. Recurring feed problems indicate the copier/separation pad is worn. See Ordering HP parts and accessories to order a new separation pad. See Replacing the device separation pad for more information about replacing the separation pad.
