Query: Canon PC150 Copier - An Update

After setup per the instructions, copies were very light. Tried adjustments allowed by copier but no improvement. Removed toner cartridge and shook it side-to-side... that resulted in copies a little darker but still not acceptable. Conclusion: toner cartridge supplied with the PC150 is almost worthless.February 16: Purchased a replacement toner cartridge for $33.94 and the PC 150 makes very good copies. Toner that comes with the PC 150 is trash.
