Offline test is one of the CE mode functions and is used to diagnose prob-lems, to detect intermittent problems, or to observe the NVM contents.

2. Test Menu

a. Sensor Test

The status of the sensors are displayed on the LCD:

_ (underline) means a sensor is inactive

(box pattern) means a sensor is active.

For example, the EOF switch ON means that the printer is in the EOFstate, and the TOF sensor ON means that paper is under the TOFsensor.

Trace (Hexadecimal Print)Trace is a test function that prints all code data sent from the control unit inhexadecimal. The data stream can be analyzed by using this function.

Adjusting Character AlignmentThis function is used to adjust the bidirectional ruled line printing so that the devi-ation of the ruled lines printing from left and right will be minimal.

ConfigurationThis printer has the capability of storing user-setup default values in Non-VolatileMemory (NVM).

ProceduresThe default values in each mode shown in described below can be set using fol-lowing procedures.

1. Make the printer not ready state by pressing Start/Stop .

2. Press Menu/Quit to enter the function mode.

3. Press Item or Item until the desired function menu appears on thedisplay.Note: The selectable function menu is different depending on the

Incorrect Print Head-to-Platen Gap Adjustment

The print head gap adjustment is 0.014 inches with the ribbon and paperremoved, and the forms thickness level in position one. This adjustment shouldbe made at each end of the platen. Do not make adjustments at the cut-awayareas of the platen.

The print head-to-platen gap adjustment is a critical adjustment. The followinginformation is intended to be used as a supplement to the 4226 print head-to-platen gap adjustment procedure found on page 5-61 of the 4226 MaintenanceInformation Manual (MIM).

Note: An error exists in the 4226 MIM.

On page 5-61 of the MIM, the following correction is needed:

The print head-to-platen gap is stated to be 0.35 mm plus or minus 0.03mm (0.14 inch plus or minus 0.01). It should be noted and corrected tostate 0.35 mm plus or minus 0.03 mm (0.014 inch plus or minus0.0001 inch).

Before starting the head gap adjustment, inspect the left and right print head-to-platen adjustment screws (reference the IBM 4226 Printer Maintenance Information Manual , page 5-61, ref. 2) for the presence of a silver-coloredstar washer located between the adjustment screw flat washer and thecarrier frame. If the star washer is present, remove the adjusting screw,discard the star washer, and reinstall the adjusting screw.

It has been found that pressure being applied to bend a feeler gauge togain access to the print head gap area when making this adjustment may flexthe platen toward the rear of the printer. When this pressure is released afterthe adjustment has been made, the print head may be too close to theplaten. The print head being too close to the platen can contribute to forms

jams and possible print head failure. The following procedure is recom-mended:

1. Disassemble the feeler gauge set and place the 0.013, 0.014, and the0.015-inch gauges needed in the gap adjustment at the top or bottomof the stack, then reassemble the set. If the set has a thumbscrew,place the gauges at the opposite end from the thumbscrew. The use ofthis method allows for a minimum amount of pressure having to beapplied to bend the gauges to gain access to the gap area as thegauges are closer and more parallel to the platen.Note: Feeler gauge set P/N 74F9666 is the recommended tool for

this adjustment.

2. Ensure that the forms thickness lever is in the topmost position, or

position 1.3. When making the adjustment at the left side, position the center of

the print head below and between the first and second leftmost upperpressure rollers. Insert the 0.014-inch feeler gauge into the gap areafrom the right side of the print head with the gauge holder toward thecenter of the printer and parallel to the platen. A slight drag will be feltwhen the gap is correct.

4. When making the adjustment at the right side, position the center ofthe print head below and between the fifth and sixth rightmost upperpressure rollers. Insert the feeler gauge holder toward the center of the

printer and parallel to the platen. A slight drag will be felt when the gapis correct.

5. Recheck the adjustment at the left and right side and repeat adjust-ment if necessary until the proper gap measurement is obtained.

6. As a final check, use the 0.013-inch and 0.015-inch gauges to verifythe gap. Using the 0.013-inch gauge, there should be very little drag;using the 0.015-inch gauge, there should be noticeable drag when thegap is set correctly.

IBM or Competitive Ribbon with Loose Ribbon ShieldCheck the hole where the print head wires go through the ribbon shield. If thebottom of the hole appears as though the print head wires have been striking it, thisis a good indication that paper has been catching on the ribbon shield. Check thedate code on the ribbon box; this can be found inside the box flap. If the date codeis not 93100 or above, a new level IBM ribbon should be obtained. Call theLexmark Supplies Quality Hotline at 1-800-426-1484 for ribbon information.

Correct Print Head Installation Procedure Not FollowedThe new print head should be pushed up against the reference stops on the carrierbefore tightening down the print head screws. If this is not done, it could changethe relationship between the print head and carrier, resulting in paper jams evenwhen the print head gap adjustment is correct.
