- The print guide warns that “Fit to page” can distort millimetre-based patterns, making circles oval and grids inaccurate.
Field notes
The symptom guide connects common print problems to specific patterns: missing colour points to a nozzle check, while crooked lines point to an alignment grid. Its instructions caution that draft mode can create false gaps and recommend comparing a reprint after cleaning; the page advises no more than two cleaning cycles before letting the printer rest. The site says patterns are drawn in the browser rather than uploaded.
