Apple Apple StyleWriter II

LaserWriter IIg Blinking Lights

I have a LaserWriter IIg. When powered on, the ready and toner lights blink in sync. It then prints the startup page, after which the paper empty light and the paper jam light blink in sync.

Any idea what this means?

I have swapped the fuser and power supply with annother working LaserWriter II, but it the IIg still has blinking lights and the other one still works fine. So I assume it is neither of these parts.

As a side note, if anyone knows of a difinitive list of what the Apple LaserWriter blinklng lights error codes are, it would be a great posting/link.

(Ironically, the blnking lights started Christmas day. I guess we didn't put up enough bulbs)
OK Paul, here it goes.
Swap out the AC power module. Thats the silver box the AC power cord plugs into.

And since youre going to have the covers off, checkout Moe's tweaking page. It's in the troubleshooting area along with the two blinking lights.

As far as the definative list of error codes for the IIg, the two blinking lights are for what youre about to do. Any other combination is either prima facie or youre looking to change out the g board. Everything else is symptomatic.

The blinking lights could be either the scanner or the fuser/ac power supply since you did get a test page. Best thing to try as Larry suggested is go to the tweaking page and tweak all the fuser and scanner connectors on the dc controller and also the two connectors on the scanner assy.

You guys are great!!

Thanks, I'm inclined to try "tweeking" the connectors. I swapped the AC Power Module again last night and the symptoms changes slightly.

Now I only the toner empty light after it has kicked out its startup page. Since I have tried multiple toner cartridges, including a new one, and since they all print fine elsewhere, I don't think its the toner.

I don't see any particular information related to the toner sensor. How is that done and what connectors might the signal pass through?

Toner is sensed through a metal rod that passes through the toner bin. The left end of it goes into the contacts on the high voltage assy. Could be bad contacts or a bad high voltage power supply.
