AI Thread Summary
The discussion focuses on upgrading the GCC XL20 printer's resolution from 600 to 800 or 1200 DPI. The user seeks a technical diagram and firmware to backup and flash the printer's ROM, specifically the Intel E28F800B5B70. They note that while the engines are the same across models, the available manual does not provide the necessary configuration details for achieving higher resolution. The conversation highlights the challenge of finding specific technical resources for this upgrade. Overall, users express frustration over the lack of accessible information for modifying the printer's capabilities.

Hello guys,
I am trying to find a technical diagram for a GCC XL20 printer. I am trying to get the 600 resolution to go up to 800 or 1200. They all use the same engines but I can't find the firmware or the utility to backup and flash the rom. they are flashabe. The roms are intel E28F800B5B70, any ideas how to get pass the buckle neck on the printer?

Looks like you could get the manual there.

Your query is already on Google.

The manual doesn't give any configuration at board level, and it doesn't show how to get the resolution any higher.


It's not a technical manual.
 

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'How Does Jaguar's 1980s V12 Dual Coil Ignition System Enhance Spark Strength?'

Thread 'How Does Jaguar's 1980s V12 Dual Coil Ignition System Enhance Spark Strength?'

I have come across a dual coil ignition system as used by Jaguar on their V12 in the 1980's. It uses two ignition coils with their primary windings wired in parallel. The primary coil has its secondary winding wired to the distributor and then to the spark plugs as is standard practice. However, the auxiliary coil has it secondary winding output sealed off. The purpose of the system was to provide a stronger spark to the plugs, always a difficult task with the very short dwell time of a...
