This is in regards to a Xerox Phaser 4500N that was purchased new around 2004 and has printed approximately 8,500 pages.
The print output is light - like 50% gray.
The toner cartridge has been replaced with a new 113R00656 cartridge and currently has about 95% toner left.
In addition, the printer experienced a bootup error and the laser assembly (084K13154) was replaced which corrected the error.
The NVRAM has been reset multiple times.
However, the print output is still light.
This printer has never had a Xerox maintenance kit (108R00600) installed.
Is the fix the maintenance kit ?
It should not be the maintenance kit, but it could be due to age (you are a long way from 200,000 impressions)
Realistically, due to the cost of that one part, and the fact you cannot be guaranteed it will fix it, I'd seriously consider another printer before I would by the part. Especially since you could buy a complete color printer for less that has way more features.
There is the toner, the maintenance kit and the fuser.
You replaced the first leaving the last 2.
Fuser would likely mean the toner would not stick to the paper, which leaves the maintenance kit.
But there are no 100% answers.
