They are described in moredetail in the Maintenance Manual.• Shift Recycle. A sliding alphanumeric pattern which identifies missing or malformed characters,improper vertical alignment, or vertical compression.• All E's. A pattern of all uppercase E's which identifies missing characters, misplaced dots, smearedcharacters, improper phasing problems, or light/ dark character variations.• E's + TOF. A pattern of all E's followed by a form feed to the next page top-of-form, which identifiespaper motion or feeding problems.• All H's. A pattern of all uppercase H's used to detect missing characters, misplaced dots, smearedcharacters, or improper phasing.• All Underlines. An underline pattern useful for identifying hammer bank misalignment.• All Black. A condition where all dot positions are printed, creating a solid black band.• Shuttle Slow. Verifies proper operation by exercising shuttle and ribbon motion at low speed.• Shuttle Fast. Verifies proper operation by exercising shuttle and ribbon motion at fast speed.• Shuttle Only. Exercises only the shuttle at fast speed.• Phase Printer. Checks for wavy print. The initial phase value is set in the factory. Run the test andcheck the quality. (The phase value prints on the left margin.) If the print looks too wavy, change thePhase Value parameter while the test is running. While the phase printer test runs, press the DOWNkey until the Phase Value menu is reached. To change the Phase Value, press the PREV or NEXTkey until the desired value displays and then press ENTER.• Paperout Adj.

Setting this parameter correctly prevents printing onthe platen.• Burnin Test. Reserved for factory use.• Print Error Log. Prints the current log of errors. Most non-routine faults (ribbon stall, voltage faults)are stored in the error log.• Clear Error Log. Clears entries in the error log.• Ethernet Test. Prints the Ethernet statistics stored on the Ethernet (if present).• Acoustics. A particular test pattern that is used to measure acoustics.• Dice 5. Pattern used to measure print density.• Prnt Ribbon Log. Prints log of cartridge installed in the printer.• Checker. For factory use. This pattern helps identify marginal printhead elements, quality of edgesharpness, and uneven print quality.• Weld Patch Log. Prints the ribbon weld log.
