Epson M 1 100 or Canon IX4000 (the price is around 1800 yuan) is recommended.
2. For color A3 copiers, Ricoh C20 10 (about10.3 million), Minolta C2 10(3.0 (about 30,000) and Konica Minolta C7 720 (about10.3 million) can be considered.
By the way, low-end black-and-white photocopiers suggest considering Konica Minolta and Ricoh brands, not Sharp, Toshiba, Canon and other brands. I hope it helps you!
