Frequently Asked Questions
How far does a 6,100-page rating go on a machine the whole workgroup shares?
Think in reams rather than months: 6,100 pages is a little over twelve reams of paper through one cartridge. A small team sending everyday letters, invoices and reports to the machine might see that stretch across a full quarter, while a desk that prints a thick morning batch every day can work through it in a few weeks. Copies count against the same total — every copied page uses toner just like a printed one — while scans sent to email or a folder use none, so a scan-heavy office will get noticeably more calendar time from this cartridge than a copy-heavy one.
What does the $53.15 price break down to page by page?
Dividing $53.15 by the 6,100-page rating gives about 0.87 cents of toner per page. That figure is the simplest way to judge this size of cartridge: it sits in the middle ground between small starter-style units that need swapping constantly and bulk buys that tie up cash on a shelf. If your own pages run heavier than standard text coverage — dense contracts, large bold headings, solid logos — your real cost per page will land a little above that mark, and lighter everyday correspondence will land a little below it.
3655 or 3655i — does the letter after the number change which cartridge you need?
No. Both variants take this same black cartridge, the 106R02736: the WorkCentre 3655 and the WorkCentre 3655i. The difference between the two machines is in their feature set, not in the toner bay, so there is no separate ordering decision to make and no risk of picking the wrong sibling. If your department runs one of each side by side, a single spare on the shelf covers both.
Why is there only a black option to choose from here?
Because this platform is a monochrome one. The machines this cartridge serves print, copy and fax in black only, so there is no color set to keep balanced, no single empty color holding up a job, and no need to stock four units where one will do. Ordering stays correspondingly simple: one cartridge type, one color, and a reorder decision that depends only on how fast your team works through black pages.
What are the early signs this cartridge is running low, and what can wait until tomorrow?
Watch the output rather than the calendar. Pages that leave the machine with paler text down one side, or with the center noticeably lighter than the edges, are the classic late-life pattern for a cartridge at this stage. A short run of light pages can usually finish the day, but once ordinary documents start looking washed out rather than crisp, the useful life is effectively over — swapping promptly protects the quality of anything client-facing, and keeping the spent unit aside until the replacement is printing cleanly makes it easy to confirm the change solved the problem.

About This 106R02736 Black Cartridge for the WorkCentre 3655 Series
The compatible Xerox 106R02736 is a single black cartridge priced at $53.15 and rated at 6,100 pages, around 0.87 cents per page. It is written for the shared-machine reality of the 3655 series: a multifunction unit in the middle of a workgroup, fed a mixed diet of prints, copies and faxes all day, where toner planning is really about never leaving the team without a working machine. One sensibly sized cartridge, one straightforward reorder point, and output that stays consistently black from the first ream to the last.
