45 ppm color A3 MFP with native 1200 dpi, dual-core controller, 3.5 GB RAM. Modern Kyocera generation replacing the 4550ci.
Most printer pages just tell you what a printer does. Here's the honest version: when this machine is the right choice, when it's fine, and when you should look at something else. We sell a lot of these for a reason, but the reason is not "every office."
The Copystar CS 4551ci is the generation that replaced the 4550ci. Same 45 ppm color and black, but first page out drops to 3.9 seconds black and 5.1 seconds color, and the controller is meaningfully faster: dual-core 1067 MHz, 3.5 GB RAM, 160 GB HDD. Native 1200 x 1200 dpi (a real upgrade from the 4550ci's 600 dpi). Paper capacity expands to 7,650 sheets with optional decks; standard ships with two 500-sheet cassettes and a 500-sheet bypass. Supports A3 (12x18). Mobile print, optional fax, optional data security kit for HIPAA-style requirements. The regret: at 200,000 pages monthly duty cycle this is overbuilt for many offices, and the price reflects it, so be honest about your actual volume before specifying this over the 3551ci or smaller.

Three ways to get this printer, each priced to match how you actually use it. Most small offices lease because toner and maintenance are bundled. If you know what you need, buy outright. If you already own one, just reorder supplies.
Final lease rate depends on term length, credit profile, and bundled supplies. Outright purchase and supplies pricing varies with bundled warranty, install packages, and order volume. Request a quote for exact pricing.
