Khaali page kaise pehchana jaata hai?

Har page chhota render hota hai aur har pixel ek darkness cutoff se milaya jaata hai. Ink maane gaye pixel ka hissa coverage hai, aur threshold se neeche wala page khaali maana jaata hai.

Kitni coverage khaali maani jaati hai?

Default 0.35% ink wale pixel hai, jo scanner ke aam shor se upar hai aur ek line wale page ko bacha leta hai. Saaf digital PDF theek shunya naapta hai.

Mere scan ke har page par kaala kinara kyun hai?

Scanner ka dhakkan ya sheet ka kinara glass ke kinare par chhaya daalta hai. Bahar ke 2 se 5 pratishat ignore karne se wo naap se hat jaata hai, export par asar nahi.

Kya rakhe gaye page dobara compress hote hain?

Nahi. Page jaise hain waise naye document mein copy hote hain, text select hota rehta hai aur images ki quality bani rehti hai — sirf page ki list badalti hai.

Kya isse khaali ke bajaye separator sheet hata sakte hain?

Apne aap nahi, kyunki separator par aksar barcode ya rang ka block hota hai jo content ginaa jaata hai. Un thumbnail ko haath se chun sakte hain.

Blank Page Remover ke baare mein

Ek taraf chhape kagaz ke dher ko duplex scan karne par aisa document banta hai jisme har doosra page khaali hota hai, aur unhe haath se dhoondhna wahi kaam hai jo kisi ko nahi karna chahiye. Dikkat ye hai ki scan kiya page kabhi sach mein khaali nahi hota: usme kagaz ke dhabbe, lamp ka halka grey aur aksar wahan ek kaali patti hoti hai jahan sheet khatam hui. Isliye yahan khaalipan naapa jaata hai, maana nahi jaata. Har page render hota hai aur ink wale pixel ka hissa gina jaata hai, threshold aap badal sakte hain.

Har sheet ka khaali peeth naap se milta hai, page number se nahi.

Common errors aur troubleshooting

Halke pencil ya halke letterhead wale page hat jaate hain. — Threshold kam kijiye taaki kam ink bhi content maani jaaye. Har thumbnail ke neeche ka aankda batata hai kaunsi value unhe rakhegi.
Sach mein khaali page bache reh jaate hain. — Scanner shor daal raha hai. Threshold thoda badhaiye, ya ignore kiya jaane wala kinara badhaiye agar nishaan kinare par hain.
Sirf text wale PDF mein har page khaali dikh raha hai. — Dekhiye ki page render ho bhi raha hai — gayab font wala document khaali aa sakta hai. Thumbnail dikhate hain ki kya naapa gaya.
Download button available nahi hai. — Ya to hataane ke liye kuchh nahi chuna gaya, tab export sirf copy hoti, ya sab chuna gaya hai, jisse khaali document bachta. Thumbnail par click karke faisla badliye.
