Page 283 Quick AFTA Service Check and Adjustment This ’quick’ AFTA Service Check can be used to verify the correct print gap on new printers and mechanisms NOT yet disassembled. If a printer has been disassembled, the “Power Off Check” on page 286, should be used first to verify that all the hardware is mounted and working correctly.
Page 284 b. Test: Slide a sheet of 1-part paper up past the carriage. Using the AFTA Wheel, close to a very small gap. The paper should be pinched by the carriage; it will NOT slide when pulled backwards. As you continue to pull on the paper, begin to rotate the AFTA Wheel in small increments to open the gap.

Power Off Check: Perform this check if the AFTA indicator wheel (wheel), AFTA motor, gears, carriage shaft, or platen have been removed at any time for service.
Page 287 Figure 54. AFTA Indicator Wheel. Notice the position of the pointer on ’1.’ 1. To gain access to the wheel, remove the left side cover. 2. Verify the smooth rotation of the wheel. Hand cycle the wheel clockwise (as viewed from that end of the printer) to a higher value, until the mechanical stop is against the frame.
Page 288 When you grasp and attempt to move it, the carriage shaft is correctly adjusted if it turns freely but does not click at the frame. Ensure both screws that secure the carriage shaft retainer are tight. To achieve the correct adjustment, loosen the 2 screws of the carriage shaft retainer to relieve the bind. Bias the carriage shaft retainer toward the lower carriage shaft retainer screw (the 5 o’clock position), and retighten the screws.
Page 289 6. Inspect the printhead cable for damage and a poor connection at the printhead. Replace the cable, if indicated. Power On Check: Perform this check only after completing the “Power Off Check” on page 286. Verify AFTA operation, using single-part forms 1.
Page 290 3. With loose forms, back fold the beginning of the forms along a left-to-right perforation. 4. Mount these forms onto the tractor pins. The printer now has a combined paper thickness of approximately 0.2 mm (0.008 in.). 5. Perform a Load operation on this double-thickness of forms. After performing a Load, the wheel should repeatedly go to a numeral that is 1 greater (±...

Checking Carriage Casting-To-Platen Gap 1. If installed, remove the front tractor. 2. Slide a single sheet of 20 lb (80 g/m ) paper through the gap between the carriage casting and the surface of the platen. The paper should slide through the gap with the slightest resistance. If the gap is acceptable, adjust the wheel position to get the pointer to point to '1' on the wheel.

Sensor Service Checks You are here because the printer displayed a '02/002/020/099 FORMS JAM' message, or an unrecoverable '01/001 END OF FORMS' message. Note: If the printer displays a 01/001 END OF FORMS message after you load forms, proceed to “Paper Presence Sensor Check”.
Page 297 If the printer displayed a '02/099 FORMS JAM' message while an operator was performing a Park operation, advise the operator that the forms perforation must be torn off at the tear bar before confirming the Park operation. The error occurs when the printer backs up the forms, but does not detect that the paper is back on the tractor.

Appendix B. Supplies, Forms, Paths, & Environmental Considerations Overview This section outlines some of the information that IBM provides to the customer in the 4247 Model A00 User’s Guide . Supplies Ribbon cartridges and paper are the only supplies you need for your printer. At the time this information was printed, the correct IBM part number for a ribbon cartridge was 1053685.
Page 532: Choosing A Forms Path For Special Forms
Note: IBM recommends selecting first the front push then the rear push as your choices for forms paths. The 4247 Printer can print on various sizes, dimensions, and weights of forms. IBM recommends you test all forms for your application before ordering large quantities. Use Table 107 on page 533 when you are choosing which path to use for special forms or paper.
Page 533: Other Considerations For Forms
Consider the following items, unless Table 106 or Table 108 provides other direction. v IBM recommends you test the Park function when you intend to run multiple-part forms. If you notice forms feed problems, try using the Eject function. If using the Eject function is ineffective, disable the Park function, and use the push pull forms path.
Page 534: Forms And Paper Specifications
Table 108 on page 535 lists various paper and forms specifications. The customer’s forms should meet the following specifications. Note: With the addition of the optional ASF, the 4247 can print on individual sheets of cut-sheet, xerographic paper and on envelopes. Refer to the 4247 Printer Automatic Sheet Feeder Guide for paper information.

Page 537 Try the forms first. To minimize parking problems, discuss your needs with your forms supplier when selecting forms. 4. IBM does not recommend continuous forms with adhesive labels. 5. Model A00: To prevent the separation of labels from continuous-forms when using the Tear or Park keys, set FRONT TEAR=NO or REAR TEAR=NO in the Power On Configuration menu.
Page 538 Cut-Sheet Paper The following sizes of cut-sheet paper may be used in the Manual Sheet Feed paper path: A5, A4, A3, A2, Letter, Legal, Executive. For optimum performance, restrict printing to 12.7 mm (0.5 in.) from all edges, holes, or folds on the paper. The term length applies to the paper dimension parallel to the paper motion.
Page 539: Forms Stacking Recommendations
Forms Stacking Recommendations IBM recommends the following maximum stacking height when stacking continuous forms on the same work surface as the printer. Appendix B. Supplies, Forms, Paths, & Environmental Considerations...
Page 540: Forms Stack Input And Output Locations
For satisfactory stacking results, the distance from the printer table to the floor should be 736 to 762 mm (29 to 30 in.) and the distance between the shelf and the floor should be 381 mm (15 in.). IBM offers an optional printer stand that is specially designed for the 4247 Printer.

Page 546: Environmental Requirements
Environmental Requirements The printer operates correctly in environments that are typical of most business offices. Attention: Damage to the printer can result if you power on (|) the printer immediately after the printer has been moved from an environment that does not meet the following operating requirements. If the printer has been in such a location, ensure you move the printer to the recommended operating environment at least 24 hours before you power on (|) the printer.
Page 547: Nonoperating Environment
Nonoperating Environment The following tables show the nonoperating environment requirements for the printer. Without Automatic Sheet Feeder: Environment Requirement Temperature range 10° to 51.7°C (50° to 125°F) Relative humidity range 8% to 80% Maximum wet bulb temperature 26.7°C (80°F) With Automatic Sheet Feeder: Environment Requirement Temperature range...
Page 548: Storage Environment

Environment Requirement Temperature range 0° to 60°C (32° to 140°F) Relative humidity range 5% to 80% Maximum wet bulb temperature 30°C (86°F) Note: Ribbon performance and print quality may degrade when exposed to temperatures in excess of 41°C (105°F) for an extended period of time.
Page 549: Appendix C. Flashing The Memory Of The Model 003
It is sometimes necessary to update or ’flash’ the Model 003’s memory. This can be achieved by downloading the microcode from the IBM First Service System II database on to your computers C: drive. The code can then be copied to a diskette for future use. The microcode can be downloaded when required from the C: drive into the 4247 flash memory through the printer’s parallel port.
Page 550 At the prompt Unknown File Type, click on the Save File... button. a. At the window Save As..., select the directory folder, e.g. the 4247 folder, in which to save the file (you may first want to create a new folder).
Page 551: Downloading Model 003 Microcode From Your Computer Into The Flash Memory
1. Power-off the printer. 2. Attach a standard parallel cable from the port on the computer to the 4247. If the printer is using an Ethernet LAN card, remove the LAN attachment card to gain access to the parallel port. You can leave the attachment card slot open until you have completed downloading the code.
Page 552 5. Power-on your computer (laptop or PC). a. If the 4247 code is stored only on the diskette, you must copy the code to the C: drive. Insert the diskette into the A: drive. At the DOS prompt type: copy A: *.* C: and press Enter.
