Using Data Dump Mode Data dump mode is a special feature that makes it easy for experienced users to find the cause of communication problems between the printer and computer. The data dump mode produces an exact printout of the codes reaching the printer. 1. Make sure that the printer is turned off and is loaded with paper. 2. Hold down the SelecType button while you turn on the printer. Make sure you hold the button down until the message HEX DUMP appears on the display. 3. Run any program that causes the printer to print (either an application program or a program written in any programming language). Your printer prints out all of the codes sent to it in hexadecimal format as shown in the sample below. 0000 0001 0002 0003 0004 0005 0006 0007 0008 0009 000A 000B 000C 000D ******** HEX DUMP LIST ******** PAGE 1 1B 52 10 1B 43 45 1B 6B 00 1B 70 00 16 63 0C 1B 74 01 1B 32 54 72 6F 75 62 6C 65 20 73 66 6F 6F 74 69 6E 67 20 20 20 20 20 0D 0A 54 68 69 73 20 63 68 61 70 74 65 72 20 64 69 73 63 75 73 73 65 73 20 70 72 6F 62 6C 65 6D 73 20 79 6F 75 20 60 61 79 20 65 6E 63 6F 75 6E 74 65 72 20 61 6E 64 20 74 68 65 69 72 20 6C 69 6B 65 6C 79 20 73 6F 6C 75 74 69 6F 6E 73 2E 20 0D 0A 0D 0A 49 66 20 61 6E 20 65 72 72 6F 72 20 6F 63 63 75 72 73 2C 20 79 6F 75 72 20 62 65 73 74 20 73 6F 75 72 63 65 20 6F 66 20 69 6E 66 6F 72 6D 61 74 69 6F 6E 20 0D 0A 69 73 20 74 66 65 20 64 69 73 70 6C 61 79 20 6F 6E 20 74 68 65 20 63 6F 6E 74 72 6F 6C 20 70 61 6E 65 6C 2E 20 0D 0A .R..CE.k..p..c.. t..2Trouble shoo ting ..This chapter discusse s problems you m ay encounter and their likely so lutions. . . ..If an error occurs, your best sourc e of information . . is the displa y on the control panel. . . 7-48 Troubleshooting
