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. In data dump mode, the printer produces an exact printout of the codes it receives. 1. Make sure that paper is loaded and the printer is off. 2. Hold down the SelecType button while you turn on the printer. Make sure you hold the button down until you see message HEX DUMP on the display. 3. Next, 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 the codes it receives in hexadecimal format, as shown below. 0000 0001 0002 0003 0004 0005 0006 0007 0008 0009 000A 0006 000C 000D ******** HEX DUMP LIST ******** PAGE 1 16 52 10 16 43 45 18 68 00 16 70 00 16 63 OC 1B 74 01 1B 32 54 72 6F 75 62 6C 65 20 73 68 6F 6F 74 69 6E 67 20 20 20 20 20 OD OA 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 6D 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 OD OA 0D OA 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 OD OA 69 73 20 74 68 65 20 64 69 73 70 6C 61 79 20 6F 6E 20 74 68 65 20 63 SF 6E 74 72 6F 6C 20 70 61 6E 65 6C 2E 20 OD OA .R..CE.k..p..c.. t..ZTrouble 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. . .
