The printer had to compress the job to fit it in available memory. Some data loss might have occurred. The message first appears when about 15 percent of the toner is remaining in the toner cartridge (about 1,500 pages remaining for the 10,000-page cartridge and about 900 pages remaining for the 6,000- page cartridge at five percent coverage). Depending on how the printer has been configured in the configuration menu, it will either continue to print or stop.
If the requested media size or type is not loaded, the printer asks if it should use another size or type instead.
