NovaJet 800 Series Service Manual

4.Is the Media Cutter malfunctioning? Remove the cutter and service station to ensure the assemblies are not inhibiting carriage assembly travel. Also ensure the cutter groove is free of debris.

5.Is the Carriage Belt tight? Is the carriage belt frayed? Check the frame tensioner and idler for damage - ensure tension is tight on belt and not loose. Clean inside of carriage belt with isopropyl alcohol (greater than 70% alcohol only!). Ensure carriage belt is installed properly with the idler (wheel) installed right-side up. Also, the block on the carriage belt should be aligned to the right carriage assembly studs or a vertical line may show in the prints. Refer to ‘Carriage Assembly’ removal procedure.

6.Is the Frame tensioner attached properly/broken? Ensure the ink delivery system electronics cover is attached to the carriage assembly properly and is not rubbing against the rear support bracket (rear white cover). Power unit off and slide back and forth to test this. Does the carriage assembly move back and forth freely without hitting any obstacles (including the pinch roller assemblies)?

7.Run the Servo Cycle Test (set for 100 cycles) under the Diagnostics Menu; if the tests were successful then check the firmware version. If the carriage assembly moves only 1- 3" (2 to 8 cm) from the home position at power up then the servo motor is most likely defective. Also, see step 10 below.

8.Power off the printer, move the carriage assembly to extreme left- hand side of unit. Power on the printer. If the carriage returns to the service station on the first pass then the trailing cables (large flat white cable) are probably good. But if a ‘carriage axis error’ occurs the faster return pass then first suspect worn carriage cover bushings, then check internal right and left carriage bushings. Replace bushings (4 total) as required; verify shims are in good condition. Replace shims if necessary.
