IBM 3000 manual Poor Fusing Simplex Mode, Forms Stick Together, Heat Damage Ð Printer Running

Poor Fusing - Simplex Mode

If poor fusing occurs on labels or heavy forms, increase the preheat temperature in 5° increments until the fusing is acceptable. Run several hundred feet of forms to stabilize the temperature. Check the fusing to see if it is acceptable.

If the fusing is unacceptable, increase the temperature by 5° and try printing again. If adequate fusing does not occur, the form may be unacceptable for use on the printers.

If the fusing is acceptable, examine the printed forms in the stacker to verify that the sheets are not sticking together, or that toner is not being pulled off adjacent sheets. If either condition exists, the form may be unacceptable for use on the printers. Evaluate the condition of the printed forms and consider the following:

v How long it took to print the job

v How long the forms were left in the stacker
v	How much pressure was applied to the stack
v The type of application for which the forms are used, for example, bar-code
	readability.
Forms Stick Together
v	If forms stick together or toner is pulled off the forms in the stacker, decrease the
	preheat temperature by 5 degrees. Run several hundred feet of forms to stabilize
	the temperature. Check the fusing to see if it is acceptable.
v	If the fusing is acceptable but forms stick together in the stacker, decrease the
	temperature by another 5 degrees and try printing again. If adequate fusing does
	not occur without forms sticking together, the forms may be unacceptable for
	use on the printers.
v	Adjust the Contrast switch on the printer control panel to the lowest possible
	setting that produces acceptable print quality. Remember to adjust the contrast
	setting on both printers so that the contrast is balanced between the front and
	back side of the forms.
v	Change the Forms Select setting on the stacker control panel to ªCº, if it is not
	already at that setting. Check the fusing to see if it is acceptable. If unacceptable,
	return the Forms Select to the previous setting. Increasing the print contrast may
	also improve fusing of solid areas and bar codes.

Heat Damage Ð Printer Running

If heat damage (melting or curling) occurs to forms or labels while the printer is running, set the temperature to a lower value before you continue printing.
