Adjustments
Fast time to ready
1.
Turn the printer on.
2.
When the Tektronix logo appears on the display, press and release the
left arrow, then press and release the right arrow.
The printer behaves the same as if it normally powered-up and is in its Ready
state except no ink is jetted. Any prints requested print blank until the printer has
actually warmed up.
Bypass mode (manufacturing mode)
Bypass mode allows you to access the front panel menus (bypassing the engine
and PostScript initializing processes) without having to wait for the printhead to
warm up. This way, you can reset NVRAM or read fault codes immediately.
Meanwhile, the printer continues to warm-up and initialize “in the background.”
1. At the rear of the printer, set DIP Switch 2 into the down position.
Ensure Switches 1, 3 and 4 are up. (Normal operation is all switches
up.)
2.
Turn on the printer.
The printer will not print a Cleaning Page (Phaser 840 printer) nor a Startup Page
when placed in Bypass Mode.
Cool down mode
The printer features a menu item that accelerates the cooling down of the
printhead. When the printer is turned off, it automatically gives the option of
performing a quick cool down.
1. Turn off the printer.
2. Scroll to the menu item
Shutdown For Moving Printer
and push
Select.
The printer turns off all the engine heaters and runs the fans on high until the ink
in the printhead has solidified. Then the printer shuts itself off. If you are
shipping the printer, remove the maintenance drawer. The printhead will move
to the parked position if a door is opened.
