Lexmark C510: base USB color printing with a 250-sheet drawer review

A base color printer whose options change the job it can do

The Lexmark C510 is an earlier print-only color laser for direct computer output. US part 20K1100 includes USB and a parallel interface, a 250-sheet ordinary-paper drawer and a 250-sheet output bin. Its useful role is a compatible existing setup that needs color pages without assuming the network or duplex equipment fitted to other configurations.

The deciding tradeoff is optional hardware. Ethernet, a Legal-size replacement tray and an automatic-duplex unit are separate additions. The C510n is a distinct network configuration. A family specification or photograph cannot establish that a particular base C510 has those parts installed.

Check the actual tray before choosing Legal paper

The standard 250-sheet tray accepts ordinary Letter and A4 pages. The capacity declaration uses 75-gsm or 20-pound paper. Adjust the width and length guides, load the stack with its recommended print side up and keep it below the load line. For ordinary letterhead simplex printing, the guide places the header toward the rear of the tray.

Legal and Folio need the optional longer tray 1. That tray replaces the standard Letter-size tray; it is not another 250 sheets added beside it. The optional 530-sheet drawer does not accept Legal either. These details prevent the tempting but incorrect assumption that a 780-sheet maximum applies to every size.

Automatic duplex additionally needs its optional unit. The manual lists supported sizes for that installed arrangement, but those instructions do not turn a base unit into an automatic-duplex printer. Confirm both the paper source and duplex hardware before planning two-sided Legal jobs.

Treat envelopes as a separate tray load

Supported envelopes feed from tray 1 rather than a separate included multipurpose feeder. The guide recommends a stack of 10, reducing that to seven in high heat or humidity. Remove ordinary stock, adjust the guides and engage the envelope stack-aid tabs before loading.

Load envelopes flap down with the stamp area and flap on the right, leading with the stamp-area end. The guide notes that some envelopes may feed better with the flap left, so try a small sample. Stamps in an illustration indicate direction only; stamped envelopes and unsuitable windows, clasps, coated linings or exposed adhesives are prohibited.

This special-media routine replaces the normal paper stack. Envelope support does not add another simultaneous input load or establish duplex printing for envelopes. Check the application size and media type as well as the physical guides.

Use the documented computer and confidential-release path

The base unit's direct USB connection is different from its parallel interface and from an optional network server. Match the actual cable and compatible driver to the chosen computer. The product's PCL and PostScript emulations do not by themselves establish support for a current operating system.

The manual documents confidential printing through the Lexmark custom driver. Assign a four-digit PIN using digits 1–6, then choose the user and confidential job at the operator panel and enter the same PIN. The job is held in printer memory until release or deletion and is removed after printing.

The guide describes the hard disk as an option for other resource, spooling and collation tasks. It is not identified as a requirement for this ordinary memory-based PIN routine. Check the actual driver controls before relying on confidential release, and remember that job settings from the computer may override panel defaults.

Keep speed, supply yield and maintenance separate

Lexmark declares up to 30 one-sided Letter pages per minute in black and eight in color. Those are different modes. They do not imply equally fast color work or establish a recommended recurring monthly volume, which remains unconfirmed here.

The original US starter toner set declares 1,500 pages per color. Replacements declare 5,000 or 10,000 black pages and 3,000 or 6,600 CMY pages at approximately 5% coverage per color. That basis differs from a later ISO/IEC 19798 declaration. The photodeveloper, waste bottle and voltage-specific fuser are separate service items.

This discontinued 67-pound printer needs suitable support, tray and maintenance access, a verified electrical label and compatible supplies. Choose a separately documented network or duplex configuration when those functions are essential, and inspect the offered unit instead of budgeting around unconfirmed options.
