Xerox AltaLink C8135 with four-tray module

The Xerox AltaLink C8135 with four-tray module is a floor-standing A3 color laser MFP built for workgroups of 20 to 60 users who need to keep four different paper stocks loaded at once — letterhead, plain, hole-punched, A3 — without swapping trays. It prints and copies up to 35 ppm in both color and black, scans at 82 ppm simplex / 141 ipm duplex from the 130-sheet single-pass DADF, and is rated for a 110,000-page monthly duty cycle. The four-tray module configuration delivers 2,180 sheets total across two 520-sheet adjustable trays plus two more 520-sheet trays in the four-tray module — and notably, all four trays handle up to 12 x 18 in./SRA3, which is rare in this class. The 10.1" tablet-like color touchscreen runs the full ConnectKey stack (Workflow Central, App Gallery, Fleet Orchestrator), and security is enterprise-grade (Trusted Boot, Trellix Embedded Control whitelisting, Common Criteria, FIPS 140-3, McAfee ePO and Cisco ISE integration). Connectivity is Gigabit Ethernet plus USB 2.0 standard; Wi-Fi is an optional kit. The reason you'd pick this over the high-capacity tandem tray version: tray flexibility instead of single-size capacity. The thing buyers regret: picking the four-tray module when their A4/letter volume actually demanded the 3,140-sheet HCTT — once you're past 8,000 letter pages a month, the constant Tray 3/4 reloads add up. Get the HCTT version (id 1391) if A4 volume is your driver.
