A BD identification unit of the image forming apparatus identifies whether a main scanning sync signal is a sync signal for odd-numbered line or for even-numbered line, and outputs a first or second timing edge signal. According to the timing edge signal, a sub-scan timing controller controls an output timing of an image signal to a printer controller. When the top of a page is detected based on the timing edge signal first input from the BD identification unit, the sub-scan timing controller is made enabled. If the first timing edge signal is subsequently input, the image signal output timing is controlled according to the second timing edge signal which is next input."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image forming apparatus, and control method and storage medium therefor","description":"An image forming apparatus capable of performing control so as to prevent a line registration error from occurring, even if a timing to start counting a positional deviation becomes different between ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8520258","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
